Rotate image by 90 degrees using Jqueryrotate plugin

I have the following code and i am getting an error message stating object doesn't support that property on the line where i try to rotate the images ($("#img1").rotate(90);). So wanted to know if i am doing anything wrong?Just banging my head with this error since morning....Can any one pls advise?

$(document).ready(f开发者_开发知识库unction() { $("#img1").rotate(90); });

i have put the id of the image tag as "img1".

Perhaps the jqueryrotate script is not being loaded properly.

This may be a stupid question but are you including the jqueryrotate library?

Are you sure the selector is working?

        $Items = $("#img1");

        if ($Items.length == 0)
            alert("Not Found!");
