You need all 8 different sized images for a deck at FTP.
My decks are now packaged in self-extracting installers. They automatically install all sizes of the deck. My decks can be purchased, as an installer file, at psthemes.com. They are available in the
Full Tilt by Fozzy section.
This is a screen grab of one of my deck's folders, containing an entire set of deck image sizes. You need cards0-6, and cardsmall.png for a complete deck.
I assume you are trying to install one of my decks from this thread, that shows one deck image, and used to have a Mediafire Link for the rest of the deck.
