I've got the top and right hand side. It's Looking like Stimpy from Ren & Stimpy. Don't have time to finish it yet so starting points are c23-r1, c25-r8, c24-r25.
This wont finish it be should get you far enough. Each new set of coordinates will allow you to progress further. So to enjoy it more only go to the next one when you get stuck. c20-r2, c19-r12, c9-r5, c5-r6 c1-r15/16, c4-r13, c18-r16, c16-r9.
Thanks, teesea! these hints still left me with about 17 pixels left to guess, if you keep things connected, you should be able to find the rest of the picture.
c20-r2, c19-r12, c9-r5, c5-r6 c1-r15/16, c4-r13, c18-r16, c16-r9.
