Question about transparency and cards

I am creating an overlay for an arena in my game. The overlay will show things that the characters cannot detect but that the player can. For example, an infra-red source will “cast” a translucent red zone on the ground. In reality it is simply a card with a translucent image of a red circle.

Here’s the thing - I create the image in Gimp, I can see the transparency is present, it shows up in the icon in the directory, it shows up in other programs. In Panda it is opaque. What do I need to do to make the card transparent? Is there a flag or something?

I tried the Gimp option of saving or not saving background color. No difference between the two.
