HTML slieshow output: fullscreen mode

[Tolzmann]

We want to run a by HelpXPlain generated HTML slideshow on our website by using an iframe.
To improve the quality of the slideshow, the user should have the opportunity, to see the slideshow in fullscreen mode.

Is there any easy way, to add a fullscreen mode to the "custom skin" of the HTML slideshow?

A great way would be, to enhance the player bar of the default skin by a fullscreen button.
This could be also a nice feature for the publisher options in HelpXPlain (Dialog "Publish", Format "HTML Slideshow").

Thanks for the feedback
