Instead of creating a new jQuery.fn.removeAttributes (demonstrated in the accepted answer) you can extend jQuery's existing .removeAttr() method making it accept zero parameters to remove all attributes from each element in a set:

var removeAttr = jQuery.fn.removeAttr;
jQuery.fn.removeAttr = function() {

  if (!arguments.length) {
    this.each(function() {

      // Looping attributes array in reverse direction
      // to avoid skipping items due to the changing length
      // when removing them on every iteration.
      for (var i = this.attributes.length -1; i >= 0 ; i--) {
        jQuery(this).removeAttr(this.attributes[i].name);
      }
    });

    return this;
  }

  return removeAttr.apply(this, arguments);
};

Now you can call .removeAttr() without parameters to remove all attributes from the element:

$('img').removeAttr();
