Drew,
My suggestion is that you use a file uploader website to enable your pictures to be posted. The good thing about doing it this way is that the pictures won't ever be removed sometime in the future. This forum as others, need cleaning out attachments from time to time.
The website I prefer using is Imageshack.
http://imageshack.us/ No need to register to use it. Hit the browse, click on the picture you want to post, then upload it. You can add multiple pics also and post them directly. Once the pic loads, on the bottom it says, Links to share your image.
Copy the forum code. Paste it here after your own writing. Then post it.
It will show up.
