Is there a way to completely eradicate the use of sprites in prettyPhoto and replace it with CSS(3)? This is in regard to the container and background so as to have more control over colors and looks. While sprites may display well enough on computers, you can definitely see pixilation on iPads, and presumably other tablets. You could get away from that with CSS3 to make it look more smooth, speed up load times, and enhance the control afforded to the designer, especially with color.
