How to import posts from another site into a wordpress blog?

Question

PHP

There is site A with WordPress CMS, which has posts and an RSS feed. There is a site B with CMS WordPress, in which you need to import all the posts from site A with the distribution in certain categories. How to do it?
It is important that all pictures are stored on the server of site B and preferably at the end of the news there is a link to the source. Is there a plugin for WP that will allow you to do this?
