Thanks for the feedback. I agree with everything you are saying.
I've been using 4000x2000 images - the exterior images are usually around 1.5 to 2MB in size depending on trees and such. The interior images are usually between 700kb and 1.2 MB in size. I'll have to try the 5000x2500 if I can get the compression right.
Yeah, I need to work on the tripod cap. I've spent more time working on my photo skills (still need work ) now I need to work on creating buttons, skins, tripod caps...etc...
