I upgraded to 7.5.9 and have ImageMagick resizing and optimizing images in my Gallery forums. But I'm having a problem. When more than one image is uploaded per gallery post, the gallery list of image posts shows no thumbnail for the multiple image posts.

It would be much nicer to have one of the images shown on the list page. How can I get that to happen?

I'd like to allow multiple images in a gallery post to show front, back and detail images to enhance the discussion about an item.
