Alternate images

Format: (media_query): (filename) [crop] [gravity] (...)

Example: tablet: img_cropped.jpg mobile: img_cropped_more.jpg

Optionally specify any number of alternate base images for given media_queries. This is called art direction, and is one of JPT's strongest features.

Give your images in order of ascending specificity (The first image is the most general). They will be provided to the browser in reverse order, and it will select the first one with an applicable media query.
