Download the latest Windows release and unzip it at your EDOPro folder (Default should be something like C:/ProjectIgnis/).
Since I can't test non-windows compilations you will need to download the source code and compile it yourself. Then put the compiled file at your EDOPro folder.
If you run the program and read the instructions you should be fine.
But for short:
Insert the name of your deck (without the .ydk extension) when asked to download all the images of the cards in it.
Insert /allcards to download images for all cards. Will probably take a while.
Insert /allfields to download artwork of all Field Spell Cards.
Insert /help if you want to know anything else.
