Tried to post a GIF file this evening, but . . . . I'll try again. Far as I can tell the file successfully uploaded to the server, but I can't get it or a very small JPEG "test" file to display.

I'll try again -- you'll be able to "read all about it" right here.

NOTE: Speaking of accessibility, check out the "furore" comparison of the two file formats, toward the bottom of the JPEG entry at wikipedia.org
