The problem is with your web server configuration. What web server do you use?

I use apache 2.4

If you have installed Magento 2 into a subfolder then you need to do some special coniguration in .htaccess files.

Here is my working example for the /store subfolder: https://mage2.pro/t/23

If you are using mod_fcgi instead of mod_php then you will have trouble with images loading with a default installation of Magento. This is because mod_fcgi requires a few different settings in .htaccess (there's more than one of them if you look in subdirectories). Take a look at your error logs and that will give you details if this is indeed the issue. One of the changes is that +FollowSymLinks needs to be changed to +SymLinksIfOwnerMatch.
