I like having my screenshots uploaded. I have my baby cam that I will take screenshots of sometimes. Since screenshots are saved as PNGs, a setting in the auto upload section to allow PNG uploads (screenshots) would solve this issue.

I'll take this and try to add different options on what to auto upload.
