To explain further, when a large image is displayed the entire thing (not just what is on the visible screen) is rendered. On large maps this can cause significant processor lag. Try to cut up the image into 3x3 (or more) sections. While some people would like to do only 2x2 (four) sections that has the problem that, in the middle where all four sections meet, they will all be rendered and thus have the same problem as the original image. Also: try not to use PNGs for large images unless absolutely necessary. They really give processors a fit. - Gauss
