One possible approach would be to use a customised QNetworkAccessManager 
(QNAM) subclass that logs all image requests. To get an idea on how to do this 
see the following blog entries:

http://www.kdedevelopers.org/node/4210
http://www.kdedevelopers.org/node/4237

Essentially all you have to do is to inherit your own class from QNAM and 
override the createRequest() function. In your specialised version look at the 
contents of the request, decide if it is requesting an image or not and then 
log it.

HTH,
