I tested it with inline GIFs in Netscape, and that works, at least. I'm
waiting on Webspace for Win 3.1 to see if it works with that.

I think it's a bit impractical in the long run, though. If

I agree. This is nothing but a complete kludge to try to make 1.0
usable *now* over tight bandwidth. But I'm tired of waiting, so I'm
trying to think of whatever I can to make things work with what's here
now. I hope this will only be a temporary distraction from making
things work better in the future.

Take the CGI option I was proposing: there's no reason it
couldn't use either a user's local file (if path is specified) or
a remote server file (if the user doesn't have the library). That
way anyone can use it, but if you download the library, you can
use it faster.

While running every hit through a CGI script is a pretty ugly
solution, it's at least flexible for the end user.

I'll try to put up a proof-of-concept URL in the next few days to
show people what I mean by all this.
