I say use the high resolution image and cache it (since it will never change). Also, this is big picture forum - not like a programming forum where it is mostly text and images are sparse to keep bandwidth low. The browser will likely cache it anyways, and a high resolution image would look much much sharper and will not effect page load times. Not many people on dialup anymore.
Nice job, though!
Is there a link to the portal page anymore?
