Can I modify multiple data records at once, in this case image data that I messed up while trying to modify a form?
Using Jamroom
The gallery_title_url field is auto-generated.
If you give your gallery the title "Cute Cats doing weird stuff" then the gallery_title_url will be generated from that, it will be something that is valid to use as a url, like cute-cats-doing-weird-stuff.
If there was no gallery_title when the gallery was created, then the gallery_title_url would not have been created.
If you turn the gallery title back on and update the image, the gallery title url will be auto-generated again.
