I assume that you'll be locating each record in the following manner...
myimage_detail.php?image_id=32
Right?
If that's the case and you're not using any specific SEARCH criteria on your "results" page, then you can simply remove all of the
Paramimage_id
Paramimage_id2
ParamSessionimage_id
From your Recordset - Variables section in Dreamweaver.
All that really matters is
Paramimage = $_GET['image_id']
The SEARCH (form) on your details page is controlled by the additional variable parameters that appear to be producing your errors.
Something like that should resolve the errors I think.
