you can create 3x3 grid of images using css.
.block { width:33.33333%; float:left; display:block; }
.block img {display:block; max-width:100%; width:100%; }
If you really want to warp the images when the page loads you can use jQuery to set the images to 1/3 the window height and width. Throw in a .resize() and it responds to changes in the browser after it's loaded.
