What do you when you cannot find the artist of something?

Reverse google image search?

I'd also use image search. It's surprising how often it finds the same picture but with more information about it (who or what is on it author etc)

Jup. Open the Google image search in a new window, then drag and drop the picture into the search field. (The image you want the artist of, not the signature.)
It works best if you have an internet source for the picture, since it will take the page where you found it into account as well, but you can also upload it from your PC and see if it can find similar pictures or a source. (If you didn't change the name of the picture when you saved it)

Or, just show us the original picture. It might be easier for someone who knows the artist to identify one of his works than the signature...or at least someone could give you keywords to search for, say, if it's a special style like "art nouveau" or "trash polka"...

I tried the reverse image before even asking here. The problem is the source image (where I first saw it was an avatar here) was about 100x100 the max size of an avatar on most forums.

Google helped me find the image in 726x584. Wow I feel stupid I just checked the title and it says "artist-[name]". A quick search led me to a blog page where it has works that look similar to it.
