Thanks again. Ok I kept trying and I have it working. Kind of... My guess is though that this is not the solution to my problem. I may have 50 large images in my HashMap cache at the end. That will still mean I run out of ram at the end. My actual aim was to load an image, then dispose of it and free up the ram and so on. How can I do this with loading these 50 images at random?

Thanks for any suggestions


HashMap pictures = new HashMap();  // your cache  
PImage bigImage;

void setup() {
}

void draw() {
 if ((bigImage != null)&&(bigImage.width > 0)){
   image(bigImage, 0, 0);
 }
}



void keyPressed() {
 if (key == BACKSPACE) {
   bigImage = getPicture("something.jpg");
 }

 if (key == ENTER) {
   bigImage = getPicture("100_0011.JPG");
 }


}



PImage getPicture(String filename) {
 if (pictures.containsKey(filename)) {
   // already loaded
   println("already exits");
   return (PImage) pictures.get(filename);
 }
 else {
   // load and remember
   PImage image = requestImage(filename);
   pictures.put(filename, image);
   println("sa");
   return image;
 }
}

Hello,

Did you finally find a workaround??

I might have the same problem, and I was wondering if you have any new ideas about large images..
