Upgraded from 1.6 to 1.9 and got this now

After a week of debating we dove into it and did the upgrade, everything seems ok when going to our site eccolights.com (don't do the www. for now due to good old godaddy screwing our dns up, but getting that fixed now).  The issue is when clicking on any category we created we get this error:

Server Error in '/' Application.
A generic error occurred in GDI+.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Any thoughts or ideas on a fix?  

Thanks in advance!

The admin side seems to be fine as well but just noticed when I try to "edit" any products I get what looks to be the same error:

Thanks for any help!

Ok!  Possibly got things fixed up here =)

When upgrading the permissions were changed and set the "images" folder to 777 and all is good it seems so far =)  

Gotta love it when you answer your own questions =)
