I see there is a lot of info on how to save a websites to an image with PHP, however I cannot find any information on how to take a screen shot of a website using a specific width.
I want to take a screen shot using PHP of my websites in different widths, so I have screen shots of the design in different responsive modes (Desktop, Tablets, Phones).
Does anyone know how to save a url to an image with a specific width set, using PHP? (or with help from Javascript/jQuery for all I care)
