Nope, it's been discussed. It's both a slight security measure and also a way of conserving bandwidth for some that don't have unlimited data plans (other carriers).
Probably well worth the dollar or two if someone can come up with this app. Maybe a simple app that automatically simulates the "GET IMAGES" function on the BB. Even if you make it free, I'm sure the fame and all the people thanking you will be well worth your time.
