Setting up the images took time and so just re-picking new images was undesirable.

However, after you pointed out that the pictures in the same location actually moved with the file, this kindof handled it. I thought I tested this and it didnt work, but it does as you describe.

One way to enable editing the path would be to make the listbox item double clickable to open the opendialog for setting a new path. (though I dont find this behavior in MoI anywhere else).

I'll explore a bit and post back.
