loading a 320x480 (which will be a 512x512 texture in memory, using 1 MB of memory unless 16-bit or PVR compressed) from file will cause a noticeable lag. If you're doing an action game you will have to preload the background images. This will leave you with little memory to go with for the rest of the game (15 images x 1 MB = 15 MB of maybe 25 MB available memory).

it is true...?

If you need lots of background changes I'd go with a different approach and either use pvr.ccz or a preloaded texture map to build up variations of the background image.
