Given this latest information, I'd be rather hesitant to even try using
Google's images as our
network traffic is all NAT'ed and all student traffic from a campus
goes out one ONE NAT address
and ALL staff traffic on another (in our case x.x.x.204 and x.x.x.205).
We currently use Amazon's images with a link back to them and have no
problem with this.

FWIW, realize that this is client-side mashup. Google will see
individual requests from individual IP addresses from everybody
viewing your page. For each IP address from which it sees requests
it'll decide whether to block or not. It'll block if it thinks you're
harvesting their data.
Wageningen University owns the 137.224/16 network, so I find it
doubtful that you're all sharing the same IP address. It's probably
just your desktop IP address (or, if you're behind a NAT device, the
address used by that device - but that's probably only a small group
That makes it even more concerning that Google's defenses could be
triggered by your development and testing activities. Do complain
about it to them. (I doubt they change their logic, but you can try.)
I've received the CAPTCHA from Google in the past a few times if I use
it as a calculator. Enter more than a dozen or so expressions, and it
thinks I'm a computer who needs help from Google to compute simple
things such as english-to-metric conversions.
I think that's a huge drawback, actually. How does Amazon's image
service work? Does it suffer from the same issue?
