I know this question might sound a little bit crazy, but I tough that maybe someone could come up with a smart idea:

Imagine you have 1000 thumbnail images on a single HTML page.

The image size is about 5-10 kb.

Is there a way to load all images in a single request? Somehow zip all images into a single file…

Or do you have any other suggestions in the subject?

**Other options I already know of:**

CSS sprites

Lazy load

Set Expire headers

Downloads images across different hostnames
