The first parameter pDisp refers to the WebBrowser object where the
error occurred. You can compare it to the interface pointer of the
top-level browser to see if it's the top-level page or the frame (use
COM identity comparison - explicitly query both pointers for IUnknown
and compare the results).

In my experience, failure to download images does not result in
NavigateError event.

With sufficient thrust, pigs fly just fine. However, this is not 
necessarily a good idea. It is hard to be sure where they are going to 
land, and it could be dangerous sitting under them as they fly 
overhead. -- RFC 1925
