All things being equal, I think a site is much more easily managed by confining persistent elements (not only graphics, but text as well) to the local structure of the site. I have enough trouble maintaining the various links that are supposed to be there, not to mention links that (IMHO) shouldn't... BTW, I have noticed that visitors enjoy (too much I think) the opportunity to point out _any and all_ mistakes, broken links, etc., and I get too much hatemail already to risk linking my menu or bullet graphics directly from another site. I recall stories of webmasters replacing linked photos of generic content with explicit content, which is a little over the top, but if you choose to link to someone's stuff without notifying them, I guess it's your own fault. The deciding factor for me in this case is that she asked them several times via email to stop linking to her images, but they just ignored her... I mean how much trouble is it really to answer an email?
