I have a PHP site and there is a cross domain iframe in it.
<iframe src="https://sketchfab.com/embed/f72166969def4de1acda21912ef6fe82?autostart=1&transparent=1&controls=0&watermark=0&desc_button=0&stop_button=0" frameborder="0" width="100%" height="480"></iframe>
Is there any way that i can allow my users to screenshot it? it is not a static page where user can have some activites in the iframe eg. users can rotate or zoom in the model and screenshot on certain part.
