All Icon in one image.

Like the way we handle main_block.png, should we add all image like , or into one big image.


Is it good for the loading speed?

In terms of loading speed, yes it helps as one needs to load only one image and define the image pixels.

One reason I can think of separate image is that what if we want only one icon at some specific place, in the case again the whole image is going to be loaded. So I'd suggest to leave it as it is, rest is on dev team.

we are considering the use of sprites for the next update....

However, Joker's point is actually a very important one...   what happens when you want to use the icon image without CSS definition the sprite location?

There may be an occasional reason to need a single item some where. But for the most part I think the sprites will make sense in many cases. In particular places like the reply/new post page. The editor loads over 40 images. That's 40 separate HTTP requests. For busy sites this would make a world of difference in bandwidth usage. I think the performance and resources benefits outweigh having separate files.
