About this board
Page Previews solves the core problem of users opening multiple tabs to gain an understanding of a word in the context of the subject they are reading. Whenever a reader hovers over a link to another article, a short summary of the subject, including its graphical image, is provided to them so they can decide whether they need to visit that subject more fully before continuing the current subject.
Please give us feedback on your experience using this feature so we can change and improve it. Each language is welcome in this discussion!

Empty page Previews
Can you give an example where starting from a heading is a good idea?
Let me give you an example. Every research article begins from an "Abstract". In academia, abstracts are compulsory. I want to publish a journal on mediawiki. Therefore, every article in my wiki will start from an "Abstract".
Page preview feature requirements?
Hi, are there any requirements (in size and dimensions) for images to be visible with page preview feature? I have updated logo of one page, but image is still not visible in page preview, only text, like before.
Suggestion: End Preview Text At End Of Sentence
IMHO, a much-needed improvement to the Page Preview feature would be to have it end at a complete sentence instead of at an arbitrary word limit. Here's an example for the entry Uffizi :
The Uffizi Gallery is a prominent art museum located adjacent to the Piazza della Signoria in the Historic Centre of Florence in the region of Tuscany, Italy. One of the most important Italian museums and the most visited, it is also one of the largest and best known in the world and holds a collection of priceless
This preview text would be so much better if it included the full sentence, like so:
The Uffizi Gallery is a prominent art museum located adjacent to the Piazza della Signoria in the Historic Centre of Florence in the region of Tuscany, Italy. One of the most important Italian museums and the most visited, it is also one of the largest and best known in the world and holds a collection of priceless works, particularly from the period of the Italian Renaissance.
Could you please pass on this suggestion to the developers? Thanks.
That sounds like a nice idea when you assume that you will be gaining the end of the sentence. However in reality there's going to be a maximum preview text length, which essentially changes this into a proposal to drop the first half of any sentence that would be incomplete. When viewed that way, displaying the partial sentence is almost surely preferable to not displaying it.
Thanks for the reply. I agree with your assessment of the issue, and I had thought about it too. The reason I still believe it's an issue though is because I observed that a large part of the time, the incomplete sentence actually caused me to open the link in a new tab to see what the next word was, thus defeating the very purpose of the preview. If many other users have also experienced this same behaviour, it might be worth fixing it.
To explain better, considering the example provided in my original comment, the preview ends with "holds a collection of priceless", which immediately begs the question: priceless what? Whereas, using the rule of only including complete sentences but not crossing the word limit, the preview would reduce to:
The Uffizi Gallery is a prominent art museum located adjacent to the Piazza della Signoria in the Historic Centre of Florence in the region of Tuscany, Italy.
IMHO, this brief extract fully serves the function of a link preview, without the added "discomfort" of having a broken sentence. An ideal compromise might be to add a setting to "Include full sentences only" in the page preview preferences, but I'm guessing this might unnecessarily complicate matters.
Essentially, I suppose it boils down to seeing which option more users prefer: a shorter but complete paragraph, or a longer but broken one?
Completely agree. I've been using the link preview gadget for years, and I don't recall this being an issue there.
With this new implementation we get cut off in the middle of the sentence, with the text just fading out. The reaction is to try and scroll or to try and find the 'expand' link that will complete the sentence - basically to try and get the rest of the sentence to appear. As per previous poster, this kind of defeats the point of the preview, if you need to click through to finish the sentence.
I really appreciate the design work that has gone into this, but it nevertheless feels like a step backwards, due to this issue. Looks pretty, works less well.
Please take a look at what the previous gadget did, because that worked well.
Parentheses as part of title
I'm sure this has been mentioned before, but what about article titles which contain parentheses that actually are part of the name of the subject? The page preview seems to work with chemical elements that have parentheses in the title, but looking at the preview for Brandy (You're a Fine Girl) leaves out the remainder of the song title which is in parentheses.
I think this has been discussed previously but I'm not sure what the current thoughts are on it. I've opened a ticket for discussion with the maintainers: T226323.
Currently anything in parentheses is hidden in the preview, but I think anything in bold should be shown.
Vandalized Page Previews - how to revert or edit?
I'm not sure where Page Previews pull their content from - I've found one this morning that differs wildly from the article it links. On the 2017 Honduras General Election page (link A, below), under the Supranational bodies header, when you hover over "Organization of American States", the preview text reads:
The Organization of American States, or the OAS or OEA, is a continental organization that serves to control American puppet states in the Americas. Headquartered in the United States capital Washington, D.C., the OAS's members are the 35 independent states of the Americas.
This is not an objective or factual statement, and differs wildly from the article that the OAS link leads to. The word "puppet" appears nowhere in the article source - which was where I went first in my attempt to find and revert the vandalism.
The previews feature is great, but I really hope that it is refined so that vandalism is easier to revert/address in the future.
For some reason the vandalized version remained as the active version in the page-preview cache for over 17 hours. I preformed a purge on the affected page which successfully cleared out the vandalism.
I'm not an expert on the caching, but one of the devs might want to look into why a few seconds of vandalism got stuck in the cache for so long. Is it possible the two edits were asynchronously processed in the wrong order? It would be bad if the software didn't spot something like that. A swift revert like this tends to be a significant red flag for blatant vandalism.
P.S. 220.127.116.11 thanks for the report. Any edit to Organization of American States would have fixed it. It can also be fixed by purging the page, adding ?action=purge at the end of the OAS address and loading it. Like this: https://en.wikipedia.org/wiki/Organization_of_American_States?action=purge
This problem still exists. The preview for Angolan Civil War is vandalized, but I cannot find the text anywhere in the article. It's really aggravating.

Full library for embedding in any web page
There are similar tools like this Page Previews feature, however that shouldn't stop our community from making ours. Having one official tool providing the best features in a simple way for everyone is a great idea which doesn't need installing browser extensions.
Listing the other extensions and add-ons is useful because we can review their design and features to improve our version.
Yup, that's exactly why I started/researched the list. To show how popular the idea was (proving we ought to implement something) and to glean good ideas/designs from. :-)
Think this means this feature really needs to be globally rolled out to non-registered users then... Maybe leave as an option for registered users though because some prefer third party gadgets like Popups on english that give you way more details (for editors)
- To EoRdE6: I agree that this feature would good for everyone outside beta testing (it is a tool made by many others), however this shouldn't happen too soon because it needs to be finished (main problems fixed, features added). Also an option for users to disable it on their account could be a good idea but it would be better to make Page Previews/Hovercards have the popular features of other third party tools so users would use our official tool.
My issue with that is that editors still have very different requirements to readers therefore a reader centric tool will never function for editors... Third party tools allow editors to view page history and editors and block logs and protection and tons more all from the pop-up. It's messy and ugly but for editors it's useful. Readers have no use for that information so I would support giving them this basic version that is currently available...
- To EoRdE6: I see your point but we could have these editor only stats in Page Previews/Hovercards as opt-in features enabled on users' settings pages which could get some editors to use our tool instead of competitors' ones to keep ours supported and popular.
There is also a library that can be embedded in web pages, AnandChowdhary/hovercard. (Have not tested.)

A way of permanently disabling Page Preview?
It keeps coming back and I don't want it!
Why not provide a way of permanently turning this annoyance off?
- I dont want to turn off Java. Why should I have to?
- It's got nothing to do with the cache or browser settings etc.. The damned thing just keeps resetting itself!
If you disable it, the setting should be kept in your browser's local storage. (screenshot). If you're using a private window, or if you're clearing your browser's local storage (perhaps via a privacy-extension), it will reset. Otherwise it should be permanent.
If it's not working for you, and you don't match either of those circumstances, please tell us what browser & operating system (win/mac/etc) you are using, list any privacy-related browser-extensions you use, and if possible explain how you can reliably reproduce the bug (i.e. what steps you follow after which it spontaneously resets). Thanks.
Page Previews for the Wikipedia: namespace?
I love this feature. Are there any plans to allow wikis to extend the functionality to articles outside the main namespace? I'm thinking particularly of the Wikipedia namespace on Wikipedia. When reading documents on Wikipedia policy, I often encounter "the core problem of users needing to open multiple tabs to gain an understanding of a word or concept within the context of the subject they are reading" - i.e. that issue that Page Previews so effectively solves in the main namespace. A preview would be especially helpful for the common case where a link uses a non-obvious shortcut, e.g. WP:WPEDIT because WP:GLC therefore WP:PSCI and WP:AWW...
Hm, I think this would be up to the community to decide. If a project decided this was something they wanted the we could discuss the application.
Preview image selected on Wikivoyage
Can the logic of which image is selected be controlled? What is the current logic for preview image selection? In English Wikivoyage it is taking the first image given in a listing template. This may be the first point of interest in the See section but more often than not will be the airport or train station in the Get in section, or even the tourist information office in Understand section. Would be better if it used the first image on the page or the Wikidata image, or even cropped version of the page banned. To see example go to region pages for Ohrid or Frankfurt.
It uses whatever Extension:PageImages gives it.
