Thanks for your help ArikArikArik, the problem with that method is.... 1. im not too sure how to use it :P and 2. In my original code the images are added to the tracker which waits from all the images to be loaded before it continues.

Thats the whole code for the applet- preloadin the image (and also everything that doesnt relate to this problem lol). Ive asked around and the answer I was given I wasnt satisfied with- make the files smaller/delete some- the files are already at their smallest about 10kb each. And also apparently (I didnt know this...) but due to security restirictions I wouldnt be able to increase the heap size anyway (this is to run the applet on my own... and others computers).
So Im really too sure what to do at the minute. Anymore help would be appreciated though.
Thank you!
