You need to download the cards0-xx.png, cards1-xx.png, and cards2-xx.png files as well - those are the oversized "XX" cards0, 1, 2. After you save them to your PC, they need to be renamed to the default file names (cards0.png, etc). These are the only 3 oversized "XX" images in the deck.
This might help you when renaming files, to have Windows show ALL file extensions:
In - Start > My Computer go to Tools > Folder Options.......
Then go to the View Tab - and Un-Check "Hide Extensions for known file types"
This will let u see the file extensions (table.png versus table.jpg). When browsing in "My Computer".
