Hi, to disable caching for the image itself you must set the appropriate headers on the image request itself. It is absolutely irrelevant if you're using Zend_Layout. Do you use static images, or dynamically created ones? If your images are static resources you have to look at your webserver configuration on how to set HTTP headers for specific requests - this has nothing to do with the Zend Framework then. If you use dynamically created images or images served through an action method of a controller you can use the procedure noted below.
