Hello, I've recently begun painting a custom livery for myself, and i was wondering if there is a way to flip whatever i did on the left side of the aircraft (the "correct" side of the paintkit) to the top reversed side, Do i have to move everything individually to the other side or can i flip the left side as a whole and just put it over the right side. 
& also, I have added some very intricate details to my paint, so how can I convert it to be the highest quality possible? The ones I've converted are only 2048x2048
The programs which I use are Photoshop CS5 & DXTBMP (I'm only a novice painter as you can see, so please dont go into detail or else i'll get lost  :blush: )

Thanks for reading/answering!

Put the Left in a folder, duplicate that folder. Flip it vertically and move upwards accordingly.
