Multipage icons

[David Bovill]

I'm used to creating icons with a separate icon for each image file. I've
noticed that there are a couple of other techniques in use:

   1. multi-page icons
   2. multiple icons in one image

I'm using some icons in a rev project of type 2. I think they are usually
formatted by scrolling and clipping the overall image using CSS - and i
guess I could do the same with an image in a group? Does anyone have any
advice on how to work together with a graphic designer who does strange
things to their icons :)
