can you give an example? Because Im confused, you want to download images from google, but not from the google image grabber?
Confusion aside, perhaps this will help. Google images requires a browser. The normal image grabber does not use a browser it uses raw sockets and threads.
The google image grabber uses the chromium libraries to render what is required to download images from google. So Im not really sure what your asking, but possibly the answer is that you can not do what you want to do. But Id need to see an example to know.
