Images preload for level user selects.
Level only preloads once
A typical example of this can be experienced with my Concentration game where once the first level has preloaded you can play the game while the other levels images preload.
The preloader used in the Concentration game is an advanced version of Image Preloader MKIII whereby the images relating to the level that the user chooses to play first are preloaded with the remaining arrays preloading in numerical order.
