Using QtWebEngine to save images to disk

I would like to be able to load a webpage URL and save images on the page to disk.

For non-images I can simply use QWebEngineView.load on the desired URL and it triggers a QWebEngineProfile.downloadRequested where I can specify a file path and accept the download. However, images just get displayed in the browser itself and bypass the downloadRequested.

It does not have to be elegant, but the page uses authentication and .load seems to pass that information around.

You can install a QWebEngineUrlRequestInterceptor to the profile of the page before loading anything, and use QWebEngineUrlRequestInfo::resourceType() to see if the resource being requested is an image or not. If it is an image, you can grab its URL as well from the QWebEngineUrlRequestInfo and download it.

Well, I found a workaround for now... in Qt 5.8, QWebEnginePage has a save function which emits a download for the currently loaded web page... so you just have to navigate to the image URL using QWebEngineView.load and then use QWebEnginePage.save
