Collectible Card Game Headquarters

I got the images to show up in the deckbuilder fram but when I place them into a deck they show up as card backs instead of the images they are supposed to be. SO the top half (the database) shows them fine but the bottom half (and when you play with the player) does not show anything.

how do I fix this?

Also, in general, why are custom sets so touchy to work with? I've imported spoiler text files and images for actual magic sets and never had any of the problems I run across that I'm getting now that I'm just trying to import a set I made with MSE. Images not displaying in both places and the decks I make in MSE not being allowed to play with the player just make me scratchmy head because I just can't even fathom why I get these problems here nad not previously.
