Wordpress is a free open source content management system. By using this we can do many things. But the problem is if we install a free theme it will surely have limitations. we will get full rights to edit that theme. In order access it fully we must buy it for money then only we can totally edit it and we can customize that wordpress theme. Same problem in the case of wordpress slider also. We will get limited number of slides when we will install a free theme. In order to overcome this problem we need to download a free slides how plugin. just go to install new plugin options and search for 'slide show ' and select a high rating slider from it and then you can unlimited slider banners to it and then we need to manually add the image banners. After customization we need to copy it's short code and paste it in the home page content.
