@pinkasimov I've seen this weirdness at a few people's sites. It seems to be working ok in MOST cases, including my own two development environments which makes it hard to debug for me. I CAN tell you one thing: The caroussel is datetime based. This means arrow right travels back in time, showing all thumbs ordered by posting date.
Can you please check your Image Display order in Options?
Please set it to [Date and Time for the entry] [descending order]
Changing this is likely to disrupt the caroussel in weird ways. Can you take a look at it?
I'm not sure whether I'll be able to make the caroussel work right with all possible combinations of settings.
Let me know what you find as this may be the cause of the weirdness on some people's sites (including yours)
