You do have a point. In theory. I haven't run across a case in practice yet where . . .

Ah. Well, I actually have. Among other things, the company I work for provides web access to a service which we customize for our clients. Our clients are themselves large companies. Part of the customization includes branding the site with their logos. We request that they provide us with a single logo image of a particular size and a transparent background. We use the single image in various places in, I think, three different sizes. The primary reason we choose to use one image rather than three is to avoid maintenance issues.

As Steven Wright has said, "It's a small world, but I wouldn't want to have to paint it."
