This page is not actually uploading any images, it is only sending a file name to the database.
for each file field, add a hidden form element, set the value of the hidden form element to use the coresponding column from the recordset for that image field.
then add the WebAssist -> File Manipulation -> Uplaod file server behavior.
for the default file name select the coresponding hidden form element.
repeat this for each file field.
Each file upload behavior will create a new binding group named WA Uploaded File (<field field name>), each of these binding groups will have a server file name binding.
in the update record behavior, you need to bind each image column to the corresponding server file name binding.
