Emailed data to Form, Captured Attached Images, Need to Update them to Image Field

Emailed data to Form, Captured Attached Images, Need to Update them to Image Field

I have successfully emailed data to my form using it's unique email address.  This is a great feature.  I have also captured the images attached to the file using the ZC_file field name.

What I need to do now is update another forms image field with the above captured image files.  I've tried using the update deluge script but the image field is not updated. See below

    entx = Entries[Entry == input.Entry && TrialID_Entries == input.TrialID_Entries];   
    entx.Image_1=input.ZC_File0;
    entx.Image_2=input.ZC_File1;

Am I doing something wrong?  Is this not possible?  Is there a work-around?

Any help would be greatly appreciated.
