Thanks again, Darin. That vi works, but it shows me one picture and I haven't managed to make it refresh (I have a group of pictures that I'd like to display, like refreshing that popup to show the next instead of this one). I somehow need to change the structure that handles events, right? I have managed to pop it up by closing/loading next image manually (like to show and hide to regain control over the main front panel), but I need to keep control of the main fp while having that popup always active as well, like with the generated picture vi that refreshes automatically, and allowing the refresh of the PreviewPicture vi to be controlled as I do with the generated picture (with a time delay to "keep" the actual image for X seconds and then change to the next).
