How to Improve Gallery Pictures

Oh, I would love an update to the way gallery images work because it's often source to great frustration... I've ended up building based on the angle of the main shot, and while starting the build I often check how the main image will look as a go forth. The fixed angle and frame is really restricting, and for me it also affects which lots I choose to build on. I think I might cry the day they announce custom images for the gallery, because I would like to present my work from the best angle. I know it's possible to upload custom images somehow, but I'm not really into CC and mods.
