IE adult content hider in C++

I want to make a program that hide as many adult picture as possible in any web browser. I know how to make the part of the program that will get a list of "adult content providers" and detect the picture that could be adult content but I don't know how to hook the data coming from internet before to show it on the browser. I ear about wininet that must be hooked but to hard for me. ## Deliverables 1) I need a C/C++ program (source code) that I can compile with visual C++ 6 or visual studio 2005 2) The program must allow me change the data coming from the web before they are shown, using a hook. ## Platform windows xp, internet explorer 6 and firefox 2
