Sure it is possible. As long as you have the javascript in there. You could also do it with vB lightbox. The trick is to include the javascript and in your picture you add <img rel ="gallery" href="bigimage" src="smallimage"

if you want he lightbox to display more than one image you would do rel="gallery" for each image

to use vB light box, look in showthread template for javascript, css, and the container
and in template album_pictureview you would put those 3 items

<script type="text/javascript" src="clientscript/vbulletin_lightbox.js?v={vb:raw vboptions.simpleversion}"></script>

the css and the container name.

and in template album_picturebit you put the rel
