Thanks, Lennart and John for suggestions.
I suspect that it was the right idea that ffmpeg can not do this. I would prefer rather to have a command from terminal where everything is there, not an external program (though I did them already installed and will try one day).

Well... instead of changing the time of displaying an individual image, I could instead create a number of copies of every image, according to the need (the time of display), enumerate them accordingly, and.. thats it! In other world, instead of controlling the time of display, I would rather adjust the number of copies of identical images. For a presentation with a few tens of images this is a prefectly convenient solution around the problem.
