Contributing historic old prints

[Norfolk Coaster]

I have inherited some old b&w prints taken in World War 2 and the 1950s that might be of historical interest. Does Alamy accept scans of this type of photo, and would they need to be resampled in a photo editor to bring them up to a certain file size and resolution?

They're accepted if you have archive privileges, for which you need to apply. Unless you own the copyright you can't list them as exclusive. If you don't, unless you can be fairly sure that the photographer has been dead for 70 years I wouldn't put them up at all.
