The bank has personalized credit cards now. They print up the card with a photo of your choice, either from their gallery or from an upload. Their guidelines are for a 840 by 840 pixel image but that’s a little bit confusing. They don’t seem to post any guidelines on the correct proportional sizing for a background image which shouldn’t be square, but instead rectangular.
No matter. This cropped fine onto the credit card. Which I can’t go back and review anymore for some reason. So no screen shot. My bad.
