-Breaking Changes....
+Card images!
 ---------
-We've recently remodeled how cards are stored. If your card ends with `.track_n` then you must convert this to a single file. If your `.track_1` or `.track_2` files are empty (aka all zeros) then do **not** add the zero'ed track to the file. The resulting file should have either 69, 138, or 207 bytes in it.
+Card images are now working! Place base images in a folder called `images` in the same folder as `YACardEmu.exe`, and the application will randomly choose one when the game calls to save. You'll see afterwards that a image will be placed in the same folder as your cards with your card name. The UI will also display this when picking a card. Enjoy.
