Images broken after changing to https

Hi, i got a problem with changing my site to https.
I made a rewrite rules in htaccess file but still on pages with images it told me that some content is not secure. That’s because images are still loaded with http:// . To resolve this problem i had to change Site Url to ones with https:// but after that all my images in media went broken. After searching a database in wp_posts table all http:// and rewrite it to https:// problem still exists. All other links from photo gallery plugin, filebase plugin are working fine. Only content that was loaded into native wp media library was broken.

Any idea how to resolve this problem?
Thx for a help.
