competition for ImageBot Rated 5 out of 5 stars
FTP is a great twist; I really do appreciate that option. Please consider adding support for more hosts like Pixelpipe. Their extension is clunky and their TOS is inappropriate. You have the makings of fantastic functionality and expansion
The only image hosts I favor are those that 'do not resize/resample my image' and 'allow hotlinking to the full image'
