Apparently, this is a very popular photo judging by how many people are linking to it:
You know, if you really like a picture, you can just right-click on it and save it to your own disk, then upload it to your own webserver. OR, if you don't have a host, you can email the owner of the picture and ask if you can link. The very least you can do is include a link to the owner of the photo.
The thing that blows me away is the number of people who are using that photo as wallpaper for their sites, so they're sucking my bandwidth whenever they load their page, not just when some archived Halloween post is viewed.
The picture's still up there, obviously, but I changed the name. It would be super easy for the thieves to figure out the new name, of course, but I doubt they'll go the trouble: they're lazy as well as rude.
