get yourself an account at photobucket, if you want you're own album. Or if you're just going to upload pics to post you could image shack. Once you have your images uploaded to either of those sites, they will give you a link you can paste anywhere you want, but you have to BB code for it to show up as a picture in threads. That's where you use (img)your image link here(/img), but use these [ ] brackets instead.
easy once you get the hang of it.
