Can I use MIGx for soley outputting absolute URLs of images, rather than rendering the images in a web page?

I backed everything out and put back in simple code. All pretty basic, just calling MIGx on the template. Still the modal window is blank. I notice that if I click done, there is a row created, which I can option click and remove.

This all may be with a display issue, which in turn prevents me from plugging in an image, and looking at any resulting source code to further troubleshoot my original quest.

I need to get some sleep. I may go to my plan B of just handcoding the URLs for images and pasting that code into a TV text area.

sounds a bit like a mess.
Any chance to have a short look into the manager, for me?
