I found this a few years ago when trying to make pdf files. It does all kinds of image formats, you load and image or document and it sends it back to your e-mail address as the format you select. It can be tedious and time consuming if you have a bunch of stuff, but it works. No need to have all the programs and downloads.
Pretty cool, I just used it so I could post some pics in the other bikes forum. Got .gif's sent back from stuff that wouldn't post.
