getBgImage: Simple Jquery Plugin to get the dimensions or other attributes from a css background-image

jquery.getbgimage.js

// Inspired by http://stackoverflow.com/questions/5106243/how-do-i-get-background-image-size-in-jquery, a simple jquery plugin who does the task

$.fn.getBgImage = function(callback) {
    var height = 0;
    var path = $(this).css('background-image').replace('url', '').replace('(', '').replace(')', '').replace('"', '').replace('"', '');
    var tempImg = $('<img />');
    tempImg.hide(); //hide image
    tempImg.bind('load', callback);
    $('body').append(tempImg); // add to DOM before </body>
    tempImg.attr('src', path);
    $('#tempImg').remove(); //remove from DOM
};


// usage
$("#background").getBgImage(function() {
    console.log($(this).height());
});

I know this is a year old, but I just found it on the StackOverflow question.

I got 2 things that could be done better:

First, in line 5 just use the slice() function as suggested in http://stackoverflow.com/a/12784180
Second: the remove() can't work with the mentioned syntax. It would need to be something like $(tempImg).remove(); as you want to reference an object, not an ID, which you didn't define earlier.

Other than that, thanks for the code, could use it well :)
