The default file setting should be set to whatever you want the file field value to be when no file is selected. On insert pages it can be set to be blank or set to an actual default stock photo. 
Our database field, that stores the filename, has a default value of empty.jpg which is the default stock photo. We, therefore, don't require anything in the Default File field.
We got around the Update page following this advice but, after what you've said above, I'm confused by Jason's first statement here.
an image field cannot be given a default value.you should create a hidden form element, bind the hidden form element to the image column from the update page recordset.
Then in the upload File behavior, bind the Default File Name setting to the hidden form element.
In the Update record behavior, bind the image column to the Server File name binding.

I, therefore, do no understand the point of the Default File option for Update forms. Can you clarify?
Also, if you didn't know about this workaround then wouldn't you be left feeling mighty confused about the extension?
The Update form would ALWAYS overwrite your filename.
Since you noted issues with the order of the code you should make sure the order is:1) recordset
2) file upload
3) update

Why doesn't the extension insert the code in the correct order? This is happening with Insert and Update forms at present.
Thank you.
