Bartosz, your snipped saved me too. i was about to place custom png’s when noticing that they work, but your snipped saved me quite some time.
just wanted to add: “swipeBox” worked like a charm on another website with same base theme, just a day before. i more or less copy pasted the code to generate the image list. same plugin version etc. controls don’t show up. they are there, but not visible. i fiddled arround with z-index and suddenly they all showed (even though, IMO they shouldn’t have…). i applied the css, but didn’t work and couldn’t get it to work again.
anyway, great plugin.
