I have a small website with two background images for top menu. When I bring mouse first time over a menu element it takes 2-3 seconds that second background image loaded (style link:hover background: url(secondimg.png)). For this short time user see nothing, of course it is annoying. To escape this situation I want to preload all images inklusive background images for menu elements, links, divs etc. Is there a very easy and short javascript or css trick? Thanks for any help!
