If I have background images set to dymamically rotate between a number of different images, do they get loaded into RAM at system startup, or are they constantly read from the disk as they are requested? Thanks Edit: Nevermind, I now know that images are loaded from disk one at a time, and converted (lossy from jpg to jpg...) and then stored in a system folder. I don't like any part of this. I would prefer that images be cached into RAM, and then be taken from RAM, unconverted, and used as the background image. Is there any way to do that?
