Hello! I’m building a web site for my web design business in WordPress and want to have a portfolio page that shows images of the responsive web sites I’ve built on a desktop, mobile phone, etc. An example of this is this site’s page: http://sosimplecms.com/showcase#Featured Website Designs/91617 or the following: http://www.gateserver.com/portfolio-responsive-design/
Is there a WordPress plugin to use? Or is there a web site you can go to in order to generate these images?
