- How best should the Wikipedia deal with convenient viewing of multi-megapixel images
Would the automatic resizing from "really big" to "screen size" cause the same kind of image quality issues that Tannin mentioned with thumbnailing?
Technically speaking, yes. But in practice, the difference would be insignificant and virtually invisible. Image quality problems really only start to bite when you have a small number of pixels to deal with. As a rough guide, if the destination image is:
~200 pixels: major problem ~500 pixels: minor problem ~1000 pixels: no problem.
It's probably worth doing a ''very'' mild sharpening on large resizes (by "large" I mean (e.g.) a 3 or 4 thousand px shrunk to (e.g.) 1024px), but it needs to be just a tiny touch.
