Let me explain this a little better.
If you have the picture hosted on your own website somewhere, you can just use the and [@/img]tags (take out the @ sign...sorry Curt, couldnt resist ediitting a post of yours,,,LOLOLOL-Witfull) and copy and paste the address in the middle. The address must end with a .jpg, .jpeg, or .gif
You can also upload all of the pictures into the gallery. Once this is done, look at your pictures. There is something called a UBB code. You can copy and paste as many of these as you want onto a post.
