Web pages usually consist of many images that will add a considerable
request overhead. Today sprites are used to overcome this problem, but
they are hard to manage and maintain, for example when you want to add
a new image to the sprite.

Therefore, It would be so great if this format can contain more than
one image, and at the client the intended image is specified somehow,
maybe through the anchor (#). A good interface to convert and add
images to the container is also needed.

This will be beneficial in many ways. Hidden images, or images from
other page is loaded first time, and will reduce wait time so much.
And will reduce requests drastically.

SPDY (http://dev.chromium.org/spdy) attempts to solve the problem of having multiple http connections is a more elegant way. So supporting sprites wasn't one of the goals for webp.

Having said that there have been mentions of other use cases for holding multiple images (such as resolution). So your ask seems reasonable.

There are other advantages to this:

For example when it's intended to upload an album, it's possible to do
it with just one file.
Or to archive or transfer images on external devices.
Or the one that you said, different resolution like icon format.

Maybe a partitioning design can be considered.

I'd like to see stereoscopic images too, now that this whole new 3D
thing is finally taking off.
