Hi Mark,

This is a known issue where IE would not cache the image. We renders the image with caching headers properly set and for some reason IE just refuse to cache them and it occurs particular when the image is a background image, which is your case. We have experimented and noticed that IE often started to cache them if you clear out your temp file cache, but it will soon stop caching them as if it has never seen these images.

One thing you can try is to use real image files instead of the built-in "virtual images". You can find all the image files we use in a zip file Images.zip in your installation folder. You can unzip that file to get the real images, put it on your server, then set appropriate menu properties to use those files. This way it may not be able to get the cache working, but at least it bypasses ASP.NET when the image is fetched. Thus eliminates at least one step.

We will continue to research the cache issues and see if we can find anything.

Thanks

Could you explain step by step process to achieve this as we are facing the same issue ?

Thanks
