yep, the boards don't upload, they only link to images that are already online. I personally like dropbox, drag a file into the dropbox folder, right click and copy public link, paste and you're done. And it syncs files across computers which is nice.
I just use Windows Backup in Win 7. U can choose folders and whatnot and say when to backup and where to store the backup file. But if you want a true backup/mirroring u could use DropBox as well or Dropbox Automator
screw imageshack or photobucket.... dropbox dude dropbox. imageshack is the worst. photobucket compresses your stuff. dropbox just works like both of those should, and doesn't link you to a bloated page of ads and painful load times. a great way for sharing files of all types and up to 2gb free. sorry... can't comment on…
