You can add extension .jpg access for the original photo URL?

You can add extension .jpg access for the original photo URL in a radio imput? because it has compatibility with LightBox. Example: if we replace the link /s1024/ in the picasa url to /s0/ we can use original size jpg. Thanks, excelent job.
