With the embed.htt file for the next version of the Slide Show 4 and PhotoSwipe skin I can create responsive iframes as you can see here and here.
However if I embed the index page with thumbnails I need different code because scroll-bars should be added and the dimensions are most times different from the dimensions used for the Slide page.
See here for an example.
So my request is:
implement two embed files, the current embed.htt file for the index page and a new file embedslidepage for the Slide page.
The Album menu should offer two items Embed index page and Embed Slide page.
