A quick question regarding whether or not I should ask someone to credit me.

[boycunt]

All right, so one of my icons is an animated .gif that I made from a flash file. I did not make the original flash file (in fact, I do not know the maker of the original flash file, however, I do have a "original artist unknown" note underneath the icon). However, I did decompile the .swf into frames, and I shrunk these frames/compressed them so they were icon size.

That being said, do I have the right to ask for credit for this icon? Or should I just leave it alone, since I did not make the flash I took it from?
