jQuery script to fill a parent container with an image without whitespace.
This basically emulates the background-size: cover; css property, using an img tag instead. Check out the demo to see it in action.
Simply call it on the image(s) you want resized, like so:
$('#myImage').resizeToParent();
If you want to target a specific parent to resize to, use the parent parameter:
$('#myImage').resizeToParent({parent: '.parentContainer'});
