Handy link Mike, thanks. Here's the previous discussion on this, which
includes a more sinister suggestion than Frankie's on why they might
strip metadata ;)

I agree with Tony a) that 'SEO' type motivations are not the only
carrot/stick, and b) I don't believe crawlers do use any embedded
metadata in indexing (perhaps because they find so little?). But if
they did it would surely have a major impact for those collections
that did provide it. I do know that Google uses filenames as just this
morning I found a really crucial bit of info to identify an old image
where the geographic location of another image uploaded by a user was
in the filename and nowhere else.

I think Sarah has said the IPTC is already campaigning for this, so it's down to us to make the case for it. Maybe get the Collections Trust involved?

You might not think this is a big deal, but in some scenarios, especially where you have lots of images on the page, it can add up. And the user experience of faster loading sites is always going to trump hidden metadata serving no obvious user benefit.
