Are you sure about that hard drive size, 2.2GB wouldn't really be enough to install windows on, let alone anything else.
Assuming you're wrong about the hard drive and it is larger than that then It would run it, but it wouldn't be a very pleasurable experience doing so.
The CPU is too slow really, it hasn't got enough RAM and the screen size on a netbook wouldn't be very nice to work with while doing photo editing.
£250 is going to be stretching it a little, you'd probably be looking at reconditioned to get something decent for that price.
