Please help: Organizing a field that is a list of images

Hi there, I have a field that is called listing photos

Is there a way to organize the order of the listing? also how can I remove and item from that listing?

this workflow didn’t work: (I had a rg displaying the images with an icon for deleting them)
1-make changes to a thing
2-photolist - remove - parent group image
3- nothing happens

I also tried the delete an uploaded file but it didnt work

Do you know how to delete it and organize that data? thank you
