I am using Bufferedimage however an image only displays a card(ex. 4clubs). When i try to call all the images by writing the filename(Cards) none of the images appear in the game. Any help would be appreciated!!

Does this code compile without errors? I get 15 errors.

This makes no sense to me:
what is an image supposed to display if not a card?
how can you 'call' an image?
what does 'writing the filename(Cards)' mean?
