You could simplify it to begin with....

Check the dimensions of the images are the same, if thy're not then you know before you do any more time consuming proccessing that the images arn't the same.

On the other hand if the width and the height are the same in each picture, then you can go on to set up 2 arrays containing the picture information and compare the two togeather.

e.g:

//Returns true if the images are equal
public boolean imagesAreEqual(Image i1,Image i2)
{
if((i1.getWidth()!=i2.getWidth)||(i1.getHeight()!=i2.getHeight)) return false;
//Grab the two pictures here....
//and now compare...
for(int index=0;index<picLength;index++)
if(pic1[index]!=pic2[index]) return false;
return true;
}
