Swipe on mobile?

Hi

I use your plugin for showing the gallery images as lightbox
I changed some styling, but no js or similar…
Unfortunately swiping on touch devices is not working, even though I checked the relevant settings…
Also the behaviour is a bit wierd when you turn your mobile from protrait to landscape… sometimes the pic is only some pixles big… :/

See above an example

Any idea how to get that fiexed?

Thansk and regards,
Tom
