Thread:Talk:Requests for comment/Standardized thumbnails sizes/Potential client: Extension:MultimediaViewer/reply (2)

I'll probably add 1920x1080 just to make sure we're supporting everyone, and use the full-size image for anything above that.

When it comes to panoramic images, I guess we'll need to determine that based on the aspect ratio of the thumbnail on the page - AFAIK it's guaranteed to preserve the original ratio, so that should be OK, but we'll determine whether the ratio is e.g. 3 or 1/3, and if so, use the height or width as the only limiting factor, then enable scrolling.

Good plan :)
