Image Upload from Repeat Region

I have a database table for a slideshow. The database table has several text fields and one image upload.

I use a repeat region to create multiple forms to update each of the rows based on the ID. Everything seems to work except when I update one of the rows and don't choose a new file to upload it changes the database field content to the first rows image value.

Is there something I need to add to the upload image script or is what I'm trying to do not possible?

I've included the file.

Add the current file value to a hidden form element on the page. Then set the default in the file upload server behavior to the hidden form element posted value instead of the recordset value.

Worked like a charm. Thanks.
