Hi I really need to get this resolved, i've asked a couple of guys with no luck so far, any help would be great...

I need to add an image selector to the Studio Testimonials addon (no-response form the dev) i have been able to add the database field (imageID) and add a selector to the page but i'm not sure how to change the controller to actually save the selection to the database, i've attached the two files i'm struggling with, thanks for any advice.

Ben
