if no programs or anything sh0ow up i think the best thing to do is get the original skins then just take the picture off and put some thing on
the empty spaces if you delete them on paint ?
or if you need to be more detailed ...
1. go onto paint
2. make sure when you open paint, make the random white box to the smallest size !
3. now , open each picture of the Super Card's Skin
4. Erase the skin now .
5. put anything you want now that will fit the skin
6. save it as a new name so you don't delete the skin name so you have a new file !
Note : Make sure you don't resize it or it will mess it up !
