I haven't been able to find a reference to this problem in any posts. IH2 is working fine, but I can't use the IH manager to upload images. When I browse my images and upload one, I get a blank page with the address http://www.mysite.com/catalog/admin/...if&action=save showing in the address bar.

Images zoom perfectly on the pages. I'm trying to upload a small JPG, does the reference to a GIF in the address have anything to do with it?

Thanks for the help.
