Fix flashing background images in IE6

Often, at the stage of testing a site in different browsers, I had to deal with the unpleasant effect of “blinking” background images in IE6, which manifests itself when you hover over a link that is a block element. Blinking occurs due to the fact that the browser reboots all background images from the server.

To eliminate blinking, you need to connect a small JavaScript code to the web page:

var m = document.uniqueID
&& document.compatMode
&& !window.XMLHttpRequest
&& document.execCommand;

try{
     if(!!m)
      {
         m("BackgroundImageCache", false, true)
      }
   }
   catch(oh){};
