html - Using sprites with IMG tag?

Question

I understand how to use sprites, however, isn't a "src" attribute required for IMG tags? I could always use a SPAN or other tag and set the background/width/etc but it won't be semantically correct.

Basically, I'd like to omit the SRC for an IMG tag and use just sprites, but am concerned about the HTML not being technically valid because of it. Thanks.

Using sprites doesn't necessarily mean you need to define them in css backgrounds. You can also use IMG tag sprites, to do so you need basically trim your image. There are two good articles explaining that technique:

Both CSS and IMG methods sure have their own benefits, so you need to figure out which one suits you better.
