Definitely recommend lj's scrapbook - just create a folder for the icons and maybe folders under that level for more specific sections if you want and then I usually post entries via semagic which automatically uploads them to SB and updates the links. There's also the option for imageshack or fotki on semagic too is lj's being bitchy (only ever happened once or twice for me)

Will look into my folders for pics and comment again :D
