Need help with Image Handler + Hyperlink

Okay,


I'm trying to make a prototype for my Products Page.  The example starts out with 2 hyperlinks.  When I click on the HyperLink it's SUPPOSED to perform two actions:  1)  Shows the image of the hyperlink in the Image Handler and 2) changes the URL (adds ImgID=1 on the end of the URL).  However, I cannot get this working;  2) works, but not 1).  Any help is greatly appreciated.  IF there are replies I'll put up the source code and the code-behind.
