Portfolio issues

Hi

What lightbox plugin needs to be installed because the lightbox option does not work? It just open the image on a completely blank page.

Also, when I use the Ajax preview option, all the images are shown as squares when my images are actually landscape. If I set a featured image, the thumbnail displays the full image properly but the preview shows a blown up, low quality square image. How can I set this up properly. And if I set a featured image but don’t use Ajax then the featured image shows up on the single portfolio item page but it’s severely cropped.

Do you have documentation for setting up the different portfolios because it isn’t covered in your current documentation and I find it confusing.

Thanks
