This website is made with a WordPress theme called HEAT.
By comparing at least a hundred themes I found this theme the most clearly structured with an almost perfect navigation for touchscreens.
The theme contains three main kinds of galleries, which have partly internal extra possibilities as well.
PAGES, GALERIES and PORTFOLIOS
Some galleries work perfect for PC, but extend the frame on an iPad or run much to small on the smartphone.
Sometimes swiping with the fingers runs 100% perfect, sometimes you have to TAP (!) on the picture, to let it make the first move, and then it slides smoothly.
It may need some time for a gallery (especially the PORTFOLIO galleries) to preload and switch into the correct display. In slow Bali WiFi more than 17 pictures in a so called Portfolio lets the iPad crash.
On the Windows 8 touchscreen some galleries of this theme slide with finger touch, others work only with the arrow keys.
Normally the sizes of the performance work in a good way. Sometimes it looks better, when you adjust the size with CRTL-+ and CTRL–(minus)
Regular Pages with gallery “Full Width Slider” have a symbol in the upper right corner for FULLSCREEN. That´s cool!
And as usual: In all other galleries of this theme the use of the F11 key for FULLSCREEN is available, at least in windows browsers.
It is a sophisticated piece of programming.
