Nice to see you again! This time I just found an article in Microsoft Knowledge Base that titled How to display images from a folder in a form, a report, or a data access page.
I tested it, and got the same error because I don't have the c:\temp folder. It worked once I created the folder, so the error is definitely caused by not having the specified folder (as ReneeC suggested earlier), Mr Gates II

It runs absolutely fine here. I'm unable to replicate any problem.

I knew it would. It's good code. You need to do something about a path spec but other than that, it's nice code.
