Updating an image and retaining the filename

I am using DFP with DataBridge. Each record has one image, when the record is updated and a new image selected, I want the new image to have the same name as the old image.
I have tried various things but can't understand exactly how to do this, I'd be very grateful for some assistance.

in the Digital File Pro server behavior, click the Lightning bolt next to the File Name setting and select the Image column from your recordset from the dynamic bindings.

you'll need to double check that the Recordset code comes before the upload file code in your page for this to work.

Thanks very much for your reply, I've given that a try and it results in the new file being renamed filename.jpg.jpg that is the extension .jpg is added again to the original filename.
I added code to strip off the extension of the filename from the recordset before passing but this results in the filename now being set to just ".jpg" ie extension only filename lost.

I also get:
"It appears that one of your server-side values is improperly coded. Please check this interface for inconsistencies." when I try to look at the DFP server behavior.

What am I doing wrong?

send a copy of the page please.

Many thanks be grateful if you'd take a look, page attached

try changing:

'FileName' => "". basename($row_WADAcard_crd['image_crd'],'.jpg') ."",

to:

'FileName' => "".(str_replace(".jpg","",$row_WADAcard_crd['image_crd']))  ."",

Thanks for that, I've tried it and the problem now is that the actual image is not replaced with the new one. The filename stays the same. Presumably DataBridge believes the image hasn't been changed, hope there's a simple solution to this!
