Do you use image sprites to reduce HTTP requests?

A sprite is an image that has all of your other images inside of it, so if your sprite
has 5 images, you’d be getting rid of 4 HTTP requests and speeding your site’s loading time
up by the time for each of those 4 requests latency. You will use CSS selectors for each
link to display only a portion of the image sprite - effectively showing just the
image you need.
The benefits to use CSS image sprites are:
- to save bandwidth
- to reduce HTTP server requests
- to speed up page load times
Ensure that the file size of your master image isn't greater than the sum of its pieces.
- Figure: Bad Example - four images, one for each icon
- Figure: Good Example - one image contains all the icons and CSS selectors make the browser display only the part you need
Do you feel this rule needs an update?
