Thanks, this worked but not completely
Your instructions did, indeed, solve the photo update problem but not the listOrder field problem.
When I went into the code on the Insert and Update pages, for some reason the listOrder field was not listed in $WA_fieldNamesStr or $WA_fieldValuesStr. I hand coded it in and it works now. Not sure why the listOrder was not picked up in the page generation. It was listed in the DataAssist Wizard and showed on the Details Page.
Thanks for your help
