Cards not appearing in Players' hands

I made up some small (32 x 32 px) tokens to use for some in-game currencies and made a card deck out of them. The decks appears, on the tabletop and I can deal cards to players and the number of cards is displayed above each player's avatar. When I click on the player's hand, however, the card faces don't show up, so a player can't play them on the table. The icon for the card back shows up in the dark pop-up, along with the label, but not the card faces themselves (although since these are more like tokens than cards, the back and the face are identical). Nor can I draw by dragging to the table from the deck. This is doubly odd because the default card deck works just fine within the same game, and I have other games using custom cards I've created. The files are PNGs, which should be a problem, but at first I had an alpha channel on them to give them a shadow, and I thought that might be causing the problem (even though the card backs, which have the same shadow, display as expected). So I removed the shadow and they still wouldn't display in the player's hand. Then I thought maybe Roll20 didn't like it that the face and back graphics were one and the same, so I changed the names, and reloaded the page — nothin'. So at this point the only thing I can think of is maybe the graphics are too small — but then why would the back display and not the fronts?  I'm stumped. Thanks, M.

Do you have this issue making a custom "token" deck of a different larger image? And it's only related to the picture you're using? It's happening across browsers?

Thanks, Steve. We implemented some (much) larger images and everything is working fine. The downside is they take up a lot more real estate in the UI. In your copious spare time, you might consider testing with some smaller images (32x32) to see if there's anything that can be done to make them work, as this is the only thing I can see that was different between face images that worked and images that didn't. 

Malcome, you do know that you can resize the deck in the property menu.This let's you use a larger image while having a smaller footprint on the actual table. Editing Decks is possible If you click on the name of the deck (in the deck listing of the My Settings tab) and you'll open up a dialog box with additional options and settings:  Card size on tabletop Determines the size that the cards are played to the tabletop at. If left blank, the system will automatically determine a size.
