I believe you're trying to use the IMG tag to reference them. Or, you might've cut'n'pasted the filename in your message. In either case, they're stored on your local hard drive which, obviously, we can't access (but you can, so you see 'em).
For example, in the first one, it's pointing us to:
C:\Documents and Settings\jmanus\My Documents\009_6A.JPG
Use the Attach File feature instead. You can only attach 1 pic per msg, so just keep replying to your own msgs in the thread til you're done. Alternately, you can post/host the files on a publicly available system and point to them there.
BTW, this also happened in the other thread(s) to which you tried to post pics today
