Enable editors & developers to generate & manage Responsive Images "Mobile First" via the Post Editor and in template files.
Yes...and no. The Plugin provides an interface to allow both technical and non-technical users to create Responsive Images. It does however assume at least a basic knowledge of best practices for creating mobile-first responsive websites.
You will need to configure default breakpoints using the Plugin's settings menu.
Not currently. jQuery Picture is the default script to load the images at various breakpoints and the HTML is processed to match that syntax.
In a (upcoming) future release we will provide hooks and filters to allow developers to provide their own scripts and markup patterns.
Why yes you can! Simply uncheck the checkbox box in the Plugin settings page to disable script inclusion. Be sure to re-include the script correctly though...
