Manipulate DOM model in QWebView before rendering

[pacanek]

I need to manipulate DOM model before is rendered. Let's assume I need to remove all <img> before I show them.

If I try with QWebPage::loadFinished() it will be to late and I will see flick.
If I try with QWebPage::initialLayoutCompleted() I end up with some images removed and most of 'em not.

I also tried approach with NetworkAccessManager::networkAccessManagerFinishedReply(reply) but when I try to use webview in a networkAccessManagerFinishedReply I end up with empty "toHtml()" which is understandable because we've just got a request packet and we're not in a state where it was sent to webview. Maybe there's option to edit packet in FinishedReply?

Any ideas?
