Still being fixed?[edit]

Is the extension still being developed?


Thank you for this extension. It works perfectly! --84.227.138.168 11:34, 30 October 2010 (UTC)

Does it work with MW 1.17?[edit]

The extension looks really great (considering the example) but I can't make it work. Nothing happens when clicking images. No visible errors either.

Is anyone running this in 1.17? --VNAlves 17:24, 30 July 2011 (UTC)

It shouln't work on MW 1.16 and MW 1.17 because of improper use of the regular expressions. I'm working on fixing these issues and hopefully the new version will see the light of day this Christmas. Katkov Yury 12:03, 26 November 2011 (UTC)

Does it work with MW 1.16?[edit]

No luck - Wasn't able to make this work on MW 1.16.5 / local server. Highslide in /js/highslide works fine. But nothing happens. Phcalle 21:49, 14 May 2011 (UTC)

I tried to install this extension on MW 1.16 but was not able to get it work - the folder-settings seem to be ok.

Thanks for support + greetings! --Filburt 17:23, 8 January 2011 (UTC)


The same for me ! Thanks in advance !

I changed to FancyBoxThumbs. It's very lightweight and works fine with MW 1.16...
--Filburt 20:06, 10 February 2011 (UTC)


Thanks Filburt for your reply.I tried yet the FancyBoxThumbs, but I got problems also with it. Following instructions it seems to be very easy to configure, but when I run it I don't get any error but the images aren't opened with "fancyBox" effect but are appended to bottom of the page. I also wrote to Fancy Box creator but I didn't get any answer.
Actually I'm using lightbox extension, but I have some trouble with Special:NewImages page and UsabilityInitiatve so I would like to try something else .

how to download[edit]

Hi guys, does anybody knows how to download this extension? --Katkov Yury 20:09, 13 November 2011 (UTC)

Patch for MediaWiki 1.18.1[edit]

I just got HighslideThumbs 0.1.0 running on MediaWiki 1.18.1 and made a patch for it:

http://chris.files.hobbyelektronik.org/HighslideThumbs_mw_1.18.1.diff

I don't know if the german translation of MW is a little bit off but on my local installation of MW 1.18.1 there are no title-attributes on the images, so I removed them completely from the source. So no subtitles are shown below the resized image.

Update: Some PHP-installations seem to dislike the comments in the regex-expressions. I've added another diff-file that also removes the comments:

http://chris.files.hobbyelektronik.org/HighslideThumbs_mw_1.18.1b.diff

Your Patch works for MediaWiki 1.16.5[edit]

Thanx a lot. I tested your patch on my Mediawiki 1.16.5, it's work. Here the code of HighslideThumbs.php for MW 1.16.5 :

Version for MediaWiki 1.19.1[edit]

It was needed to change some parts of the file for 1.18, because of the changes in MW 1.19. Here is the small patch (apply after you applied the patch for 1.18):
