Hi Oleh,
EPiServer 7 Blocks replaced Composer functionality and isn't backwards compatible, however carousel type functionality is widely used and you can find quite a few examples online using various implementations.
This article below details one such example of how to create carousel functionality using CMS 7 blocks to define each frame of the carousel.

This additional article details how to migrate Composer to CMS 7 if you find a legacy Composer module you prefer.
Good luck
@Steven Rowell Thanks for You help! I tried to create carousele using this blog http://world.episerver.com/Blogs/pezi/Dates/2013/5/Create-an-animating-slider-with-content-area/ but it doesnt works :(
Hello , I am looking for documentation how to create carousel with images as block in Episerver 7. I found Episerver Composer package. It already has SlideShow component. Is it possible to install it on Episerver 7 ?
Thanks for Your time !
