With all the things on the to-do list, the site programmers just haven't been able to get to this one yet. While we all work hard to try and ensure all "sensical" things get done there just isn't enough time in the day :( The reason for limits holding on the actual gallery image is I'm sure quite apparent. Each one of those could rack up into several megs in a heartbeat! For now I encourage you to just enjoy the lack of rigidness in this and to not abuse it. We do appreciate everyone's efforts and thumbnail wrestling!
