user24412: I want to make video from multiple still photos (some kind of slideshow). When I drag&drop photos from media pool, they appear on timeline, but last too long. When I select all frames, press right mouse button and choose "change clip duration" I can set some value. Unfortunately, they are changing duration but stay at previous position leaving some gaps:

Are there any other ways to set duration of all frames to the same, fixed value (0.5 second for example), and at the same time keep them all together?

user24155: You can use Edit > Delete Gaps
This will remove all gaps on all tracks. To exclude a particular track, you can lock the track before you Delete Gaps.
You can also change the default Image/Still duration before the import in the application Preferences > User  > General > Standard still duration setting
