We've recently relocated to Beijing, China. A fellow expatriate invited me to Internations which is basically Xing with a focus on people living (or having lived) abroad. As I've used the Xing Greasemonkey script to enlarge user images on mouse over for years now, I missed that function on Internations immediately.
So I created a derivative of the Xing script which you can download here (2kB), v1.1.
If you care, my shiny new Internations profile can be found here.
07.10.11 Updated to v1.1 to support Internations new NetDNA Content Distribution Network (in-cdn.net) URLs. Thanks to Marc for the prod via the comment below.
20.11.11 I've seen a new URL scheme in this image. URL ending in _e__x.jpg. If that's not an error but a new scheme, I'll update the script to support it.
