Problem with permalinks

I have a problem with permalinks in WordPress. I guess it’s problem with .htaccess file but can’t figure it out.
The problem appears after turning permalinks on in admin panel. Than I can see the pictures for example in header, only on the main page. And the same pictures don’t show up on other pages.
How can I fix it?

WordPress has this option for you to define the permalinks you wanted to use. It fixes everything that is need to have a simple permalinks. If it still doesn’t work try to install some permalink plugins. You can choose here,
