SharePoint 2013 Style Library file not accessible with read permission

Question

I have a Content Editor webpart in a page which refers some images in Style Library. When users who have read permission to Style Library are not able to view those images in page. When I give Contribute permission to that group, user is able to view those images in page. I don't want to give Contribute permission to the user.

Please suggest what I can do to view those images in page.
