JQuery - Get width: auto from inline style

I'm trying to get an inline property of an element using jquery: `width: auto`. As soon as I get the width, `.width()` returns a px value instead of `auto`. This is an example of what I need: I've an `img` with this inline style setted: ``` <img id='image' style='position: absolute; height: 200px; width: auto; top: 25px; left: 50px;' src='http://tinyurl.com/k8ef66b'/> ``` I need to wrap that image in an `a`, to make the image clickable. I need also to get the image style and move it to the anchor tag: ``` //--- get height, width and entire style var imgHeight = $("#image").height(); var imgWidth = $("#image").width(); var imgStyle = $("#image").attr("style"); //---remove inline style from the img $("#image").removeAttr("style"); //--- create the <a>, add the inline style var anch = $("<a href='#'></a>"); $(anch).attr("style", imgStyle); //--- add back to the img it's width and height //--- the problem is here: imgWidth does not contain 'auto' $("#image").css({"width" : imgWidth, "height" : imgHeight}); //--- wrap the img $("#image").wrap(anch); ``` here's a fiddle with the code: http://jsfiddle.net/cBXAz/1/ any idea? How can I get the `auto` out of that inline style? I need to give `width: auto` to the image instead of a px value. Thanks in advance, best regards
