Generate some standard sizes at upload time and let the browser scale if a funny size is demanded. Modern browsers scale photos nicely, not like the nearest-neighbor ugliness from 2002. This'll simplify our thumbnail-serving architecture, remove some DoS vectors, and if we pick the next size up makes things look better when zooming or on high-density screens. Downside: diagrams and charts done as PNGs or JPGs might not look as sharp at non-standard sizes. We should also start considering serving SVGs directly to supporting browsers, so they always look nice at any size -- and at any zoom level. (Downside of this: this means we have to start thinking about size and rendering efficiency in SVGs -- don't use a 6 megabyte super-detailed map for something that's going to be shown at 200px most of the time!) -- brion _______________________________________________ Wikitech-l mailing list Wikitech-l@lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikitech-l
