Well, it's more to do with images and memory in general. If I use the same image multiple times on a page, will each image be consolidated in memory? Or will each image use a seperate amount of memory?

I'm concerned about this because I'm building a skinning system for a Windows Desktop Gadget, and I'm looking at spriting the images in the default skin so that I can keep the file system looking clean. At the same time I want to try and keep the memory footprint to a minimum. If I end up with a single file containing 100 images and re-use that image 100 times across the gadget I don't want to have performance issues.

Cheers.
