Not sure what happened to the cards0(alt).png - but the one in your package didnt display properly. i didnt screen grab it, but it was un-readable.
The cards0(alt) in your package is a "Indexed" image. The original PNG's I make are "RGB" instead.
Here is the original cards0.png I sent you, in RGB Mode - in case anyone wants it. Right-Click > Save Image As... , LDO.
