Find a photo posting site like Photobucket. Upload your photos to that site. When you view one of your photos copy the address and then in the attachment section click image and enter that internet address.
So here is a capture of photobucket
If I right mouse on that and say to open image in a new tab it does, then I copy that link.
In the post here I put in the code [Image] The url of the image goes here then [/Image] in the post. Or in the edit section you will see UBB code and simply click the image tab and it walks you through it.
