Getting multiple images to queue and load

Programming Questions

Hi,
I'm trying to build a slideshow that will be used for over 4,000 images and have some properties like panning, zooming, jump cueing ect. For this to be possible I need to find a way to load groups of images from the 4,000 to choose from(they will be organized with letter for each group and numbers to differentiate between all the photos in the group. i.e. the first photo would be named "a1.jpg" the second "a2.jpg" I've made a sketch that will load the different groups of photos but now my problem is that every time I run the draw function the images are being loaded again slowing down the program so no effects are possible to create. I've included my sketch below and my question is, is there a way that I can load there images and then once they are loaded, move quickly between them and add effects to them?
//this runs and loads the images correctly but it has no way of being able to jump out of the loading part of the function which keeps the draw loop slow.
int x = 1;
void setup() {
size(screen.width,screen.height);
frameRate(40);
}
void draw() {
imageBank("a", 8);
}
void imageBank(String index, int filecount) {
PImage[] images = new PImage[filecount];
for ( int i = 1; i< images.length; i++ )
{
images[i] = loadImage(index + i + ".jpg" );
}
image(images[x], 0, 0, screen.width, screen.height);
x = x++;
if (x == filecount) {
x = 1;
}
}
here is what I was trying to do using a boolean to get the sketch to load all the images and them jump out of the loading function after all the images have been passed through. I can't get it to display any images.
int x = 1;
boolean loaded = false;
int i;
PImage images[];
void setup() {
size(screen.width,screen.height);
frameRate(40);
}
void draw() {
imageBank("a", 8);
}
void imageBank(String index, int filecount) {
if( loaded == false) {
PImage[] images = new PImage[filecount];
for ( int i = 1; i< images.length; i++ ) {
images[i] = loadImage(index + i + ".jpg" );
}
if (i == filecount) {
loaded = true;
}
}
else if (loaded == true) {
image(images[1], 0, 0, screen.width, screen.height);
if (x == filecount) {
x = 1;
}
}
}
any help would be so awesome,
