Newspublisher: display list of files (images) in a folder to pick from?


I want my newspublishers to see a list of small preview images from their personal folder (folder name should be determined from the value of a TV) so that they can pick one for the image-TV of their article. How would I approach that?

I cannot just fill the options of the image-TV with a (generated) list of files because the folder location is only known when a publisher opens the newpublisher form. So I guess I need a separate snippet to create an option list?

Maybe this thread helps
