There's not a whole lot here, but seeings as there isn't much I've found on ancient Israel I thought I'd put it in. It has some images of sites and artefacts from the Israel Antiquities Authority, including mosques (surprising, no?) and churches.

'Funded by the Arts and Humanities Research Council, and combining King's College London's Department of History and Centre for Computing in the Humanities with The National Archives and Canterbury Christ Church University, The Henry III Fine Rolls Project is a unique and pioneering enterprise which democratises the rolls by making them freely available in English translation with a sophisticated electronic search engine, the first medieval source to be treated in this way.'

Has some small excerpts from medieval texts with accompanying translation and explanation. Not a whole lot there (unless you pay for premium access...) but would be useful for student research into medieval Britain/Constantinople/Vikings). Some pretty images for classroom resources there, too.

There are squillions of flickr sites for history images - I won't save them all to the group. If you're looking for images though for your classes, perhaps take a look...
Not sure how much you can access here. It at least has some manuscripts that you can access images of; looks like the rest of it might be in the process of being digitised.
