How to block these requests with http:// in the params?

[packetloss]

I have a webserver W hosting photos to which i refer from websites A and B. So, i have same photos on websites A and B. What i'd like to do is display one specific photo instead of current images on website B. Can this be done with nginx ? Thanks in advance.
