If the photos won't load to the forum, then put them someplace like an account on Photobucket or Flickr (you can get those for free). They let you share images (you paste in the link on the dirt doctor form, and when it is highlighted, click the Img tag, it should show up on the page or at least take someone to the photo in the other account. If you can modify the photo so it's not huge, but about 1000px wide or less, then it won't take over the whole page when it displays.
