Must be a different script. The one that I know of only uses the filename since that will not violate the rules on 4chins. Any kind of editing of the file itself to embed a link or anything else is considered a violation. They could easily just strip all non-image data from images but it would increase load and fuck with boards that rely on that data like /p/.
All I see are the same two images with the second having a slightly higher file size.
