Deck size diffrent from the card


I would like to improve some card for a module (hannibal). In this module the draw deck in in the main map (well integrated with the board).

Is this possible to have a deck on 161x250 but card in 350x500 ?

The image have the 350x500 size but when i click on one there is a red rectangle of the size of deck and not the card.

Thanks in advance for any help
