Lo and behold, all those bytes came from someone posting one of my pictures as though it were theirs on some bulletin board somewhere!
crazy. I'm obviously going to have to do something about making my page more dynamic, perhaps with some random directory names or somesuch so that it is impossible for wankers like this twit to do this stuff. Though I must admit, it's pretty cool that someone liked my picture enough to show it to their friends. :)
http://www.omf.com/html/ubb/Forum1/HTML/005838.html is the URL of the board where it was posted. About half-way down you'll see a picture of 5 shriners (do a search in the page on "shriners" and his post is the first occurance) riding a bike. that's mine, not his. He even linked to it directly and not give any credit or anything.
