With great pleasure I switched my first (own) photo website to Sparkle (https://www.berwers.org). With some help of a wide design and a bit of myself.
It took me some time to get used to the Sparkle approach, but I really like it (but must study more). Amazing what you can do in Sparkle!
Nevertheless, what I could do in an other program I should like to do in Sparkle too.
I mean: extra zoom to see details of a photo and the possibility to zoom a photo and then immediately go to the next image by clicking on the arrow.
As far as I can see now, both things are not possible.
Am I wrong?
