are you able to post pics in other forums?  Or is the problem just in this one?

Edit**

Looks like the attachment directory is full.  Not much we can do at this point because Mitch will have to either delete pics or increase the size of the directory and i'm not sure how much room he has through his host.

So, the real solution here is to start linking pics instead of attaching them.   Go get an imgur account and start uploading all your pics there then copy/paste the IMG code to this site.
