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

Let's start by just devising some buckets and using them explicitly in MultimediaViewer, then if we find that successful we can start building it into the backend?

The traditional default selectable File: page display sizes appear to be some classic full-screen sizes:
 * 320x240
 * 640x480
 * 800x600 (default)
 * 1024x768
 * 1280x1024 (slightly different aspect ratio)

Some things to consider:
 * do these fit default aspect ratios well?
 * do we also need to bucket display density variants?
 * what about dealing with panoramic images? (very long or tall aspect ratios, work best when requesting a larger total size in the longer dimension and allowing some kind of scroll/panning) Should we set size by the long dimension, or the short dimension ('show horizontal panoramas at 600px high, however wide they are' or 'show vertical panoramas at 800px wide, however tall they are)?
