We’ve checked this page, with multiple people, on multiple Macs, and iPhones and it all works flawlessly.
There definitely seems to be something strange going on with your setup, what extensions do you have installed in Safari?
Can you try viewing that page in a private window and see what happens?
It would also be good if you could get someone else with a Mac (outside of your home network) to check the page and let you know if they see any issues.
You can see it working perfectly in the video below, this is the same as EVERY device and browser we’ve tested it on.
I checked here in U.S… Mini M1, current version of Sequoia & Safari. Doesn’t work. When first loaded, clicking on first picture, works to advanced forward by 1 or 2 then fails. Close “lightbox”, click any picture, click arrow, goes straight to first picture and then fails to advance when clicking
This is very strange 
@sbchasin and @Godber can you both try this gallery page and let me know if it works for you?
at least im not the only one…and that gallery does not work either
im on a Mac Studio M2 Max
Worked perfectly
that one I sent with just one page of images …if I use the preview browser with 3 coloumns it does not work…change it to 4 columns or more it does…thats just in the elements browser…so how can it be my set up??
not only that but on my published website any album that is not in a container works perfectly!!!
@Godber - Can you try this page in Chrome and do a screen recording of you using it? Also, do you have any extensions installed in Chrome?
it does not work in chrome either no extensions switched on
I’m not really in the discussion but this link doesn’t work for me in Safari on 15.2. Clicking any image opens the first picture and the arrows are unresponsive.
Okay, this is very puzzling, the page works in all the browsers.
Does anyone here know how to use the Dev Console in Safari? would be nice to know if there’s any errors being reported 
(none show here).
Interesting. Worked the first time I looked at it. Just went back and it now isn’t working.
UPDATE: I turned off Wipr (site blocker) and got same error
UPDATE 2 After reloading a few times, with console not showing it works, as soon as I open console, it stops working. Same errors show
I had that as well…opened on iPad then it didn’t then it did…touched anywhere outside the photo it just zooms in…also if I put finger on the photo on the iPad than move it up and down the screen behind scroll hahaha…im thinking this is a long way from finished hahah
Thanks for all the help so far, we’ve been chatting about it here and it sure is a weird one.
We’re devising a plan to find out exactly what is happening and will get back to you soon.
As a side note; @Godber are you running any content blockers?
You’ll probably need to restart the Browser to test properly, could you also view in a Private Window and see what happens?
no and I tried turning of my anti virus as well…I cant understand why it works ok if not in a container…how do you view in a private window?
Restarted Browser.
Both Private Window and Regular Window - Works until console opened, then it stops, Same error as earlier post screenshot. Close console and it works again
Brave Browser - Doesn’t Work
Edge Browser - Works
Vivaldi - Works but not correctly / well
Firefox - Works, but not as smoothly as other browsers
ok sussed private window…same
like sbchasin says edge browser work fine with a gallery in a container, flex or just dumped on a page
also tried the monster page buttons dont work but the keyboard arrows left and right do
For me Safari not working whether regular or private. I’ve turned off all blockers and same result.
Firefox doesn’t work at all - can’t even select an image
In Chrome selecting an image goes to first image and non-responsive arrows in regular and private windows.
at least its not just me
