Sounds like fun! To post photo's all you need to do is upload a digital photo to the photo site of your choice ( flickr is my favorite) and then link to the photos here.
You like by putting [img] at the front of the URL that you copy from the photo page or the photo itself -and then a [/img*] at the end. JUST DON'T INCLUDE THE ASTERIK. I had to do that so it wouldn't think those words were a photograph's URL.
If you need help still, just email me the photos at email@example.com
and I will be happy to post them for you!
