jQuery says about the .remove() method
Use .remove() when you want to remove the element itself, as well as everything inside it. In addition to the
To remove the image and the wrapper that was created during the call to .resizable, use:
$('#pelican').remove();
To remove just the ability to resize the image, while leaving the image in its resized state, use:
$('.ui-wrapper').remove();
The reason for this is that jQuery and the jQuery UI widgets do some "tidying up" during the calls to .remove(), and the resizable's destructor, producing the behaviour above.
