CSS Image Sprites Overview
Starting with v9.3, all DevExpress ASP.NET controls that use images support CSS image sprites. See the article below for more information on CSS sprites:

A CSS image sprite replaces a web control’s individual images with one composite image – a sprite image – which is a collection of multiple images. An image sprite improves application performance by reducing the number of HTTP requests required to obtain images, because only one request to a sprite image is needed to load all images contained within it. HTML elements reference the sprite image via the ‘background-image‘ attribute. The sprite used within the element is then specified by its size and offset – via the ‘width‘, ‘height‘ and ‘background-position‘ attributes.
