Nice what-if HMMWV you have created. I often wondered about making a 6X6 HMMWV so that it could perform roles similar to the 1.5t 6X6 used by the U.S. Army during and after WW2. An ideal prime mover for a small howitzer, mortar, or perhaps an anti-aircraft gun system mounted in the back (like the M16 MGMC but with wheels).
You should be able to hot-link the images from your flickr account to load and display in your post. If you need assistance, I or any of the other moderators would be happy to assist you. The other option would be to upload several of the images from your own PC to the forum but there are limits on the format, file size and number of images to attach to each post.
