Uh, here you have to load it onto an off-site place, PhotoBucket, or one of the great hosting places many people here have.
Some you have to pay money, some are free, PhotoBucket is free, I use it.
You just load it up onto your acct. and then post a link, or if you want to make it display, do the BBCode thing for it (( [*IMG] *URL HERE* [/*IMG] )) (With out the *'s in front of IMG)
If you have any questions I'm sure people can help ya out, if I haven't already.
Oh, and here at school there's 11 icons.
