Doesn't work with lazyload

I’m using the wordpress lazyload image plugin http://ww.wp.xz.cn/plugins/jquery-image-lazy-loading/ to reduce image requests on page load, however this doesn’t seem to work with categories images, either the images are all blank or they all display at once, without lazyload functions.

How can I get lazyload to work with categories images?

Thanks
