images one site html elsewhere

[A2ZWebWorld]

I'm building a series of portals. The html content is different on each domain but they use a lot of images that are constant to all. Rather than have to upload 200+MB of images to each of 12+ domains I'd sooner keep the images all in one place and use absolute references to them in the html.

Is my PR likely to be affected by doing this?
Is it likely to be classed as duplicate content?

BTW These are not xxx images but travel/tourism related.

If you're worried about it (i'm not an algo expert so I can't comment explicitly), I would create images sub-domains for each site, that all point to the same IP address - the server hosting your images.

For example

images.foo.com -> 1.2.3.4
images.bar.com -> 1.2.3.4
images.moo.com -> 1.2.3.4

and host all your images on 1.2.3.4

Having a separate image server is a very common approach for high traffic sites, the one that springs to mind is BBC News (newsimg.bbc.co.uk), and there's nothing wrong with their PR!

Cheers.
