I need to change the src for an html image tag from relative to absolute url.

I am using the following code. urlRelative and urlAbsolute are created correctly but I cannot modify the image in the last line.

What could be wrong wrong in my script?

..... // other code here



     request.done(function(resp) {

            var imgTags = $('img', resp).each(function() {

                var urlRelative = $(this).attr(src);

                var urlAbsolute = self.config.proxy_server + self.config.location_images + urlRelative;

                $(this).attr(src).replace(urlRelative, urlAbsolute); // problem here

            });
