In Ionic2, displaying insecure content with Android InAppBrowser


I need to load a page using InAppBrowser for a client.
The problem is:

=> I asked my client to change all the references to https (way more secure) but I am not sure it would be possible.
=> In the other case, is there a way to allow InAppBrowser to display all images coming from if the page initially uses https?

I already tried to change allow-intent in config.xml… without success.
