This, by the way, is an excellent example of the kind of ways in which Internet media-types might be refined to make things work better for our purposes. The content-type image/gif (or possibly all image subtypes) should have optional parameters for width and height (and possibly colors, and maybe other things I am not thinking of.) This allows that information to be passed around along with the content-type. It wasn't included originally because it's trivial to determine from the file itself -- given the email centric assumption that you have the file to look at. Unfortunately, media type registration issues like this aren't made as clear as they could be. I'd like to see this group get a better idea of the kind of things we need from media types and try to add them to the registry (as opposed to doing something incredibly stupid, like establishing our own parallel registry or just using the labels without bothering to register them.) -- Marc VanHeyningen <URL:http://www.cs.indiana.edu/hyplan/mvanheyn.html>
