Full screen slides

Sorry, Table IV-A38 Fullscreen policy

Yeah, I switched it off because I don’t want full screen to be available, which now, thanks to your modification works just as I want it to.
Unfortunately it means that when viewed on an iPad, (whichever setting I use in iv-A38) the photo displays too large (cutting off parts of it) and also off center.
As I say, if this is un-fixable then I’d like to restrict the magnification of photos throughout.
Which setting would I use to do that?

Try unticking Table IV-G6 Use hires files

@davidallen23 Pls do me a favor.
Open https://betatest.opajaap.nl/test-pagina/ on your ipad
It should display something like:

screen.width = 1920
screen.height = 1200

Check if the values are correct, even after switching to fullscreen (upper right corner) and after rotation of the ipad

Apologies, I’ve been out. Yeah, that page reads:
screen.width = 768
screen.height = 1024
in either orientation & the fullscreen icon (top right corner) does nothing in either.

Have unticked Table iv – G6
On iPad if I tap on any thumbnail in an album the photo displays too large (cutting off parts of it) and off center.

Does the screen not switch to/from fullscreen mode, regardless the lightbox display?

Can you please try https://betatest.opajaap.nl/lightbox-test/ ? I made some changes there.

Tapping on a photo in your ‘Lightbox Test’ page with the iPad in vertical mode works fine. The photo displays correctly & all the icons at the bottom work as expected although the icon at top right does nothing.
With the iPad in horizontal mode the photo goes to full screen but is too large & cuts off the bottom part. Also it isn’t centrally aligned. The icons at the bottom work OK but are overlaid on top of the photo.

According to https://discussions.apple.com/thread/5528272 there is no fullscreen mode on iPad until iOS8.

What is your version?

Confusing.
I’m currently on iPadOS 13.6.1
An update has just been released: iPadOS 13.7

Does it run correctly on iPad in normal mode?
I can detect if it is an iPad, and hide the fs buttons.

Can you try a different browser?

OK. Now using Firefox.

With the iPad in horizontal mode the photo goes to full screen

Right away after reloading the page or after tapping the fs button?

In either orientation tapping the thumbnail displays the full screen photo. There is no option to tap a fs button. When in full screen there is an ‘exit full screen’ button at top right but it does nothing.
