When the page load in the browser then every image load successfully and shows its mouse over correctly. But i have another two link form the home page.One for details of the image and another for search whcih shows the images according to a search key. But the problem is that when i click any one of thoes link and back to home page then the images again get downloading. Please reply for any suitable help.
If you are loading the images from a database then I don't think web browsers are able to cache them. If you store the images normally in a folder and store the filename only in a database then browsers can cache them and pages will load faster. Alternatively you could try adding session_start(); header("Cache-control: private"); PHP: to your headers to prevent the page being reloaded on the second visit.
