It's a really good extension because it just does what it's meant to do. It's easy to style and manage. Plus it has all layouts you would need for a portfolio. We found two minor bugs. First, the Facebook template doesn't seem to work in 1.6 but we don't really care about that anyway. The second is the links in the category list layout. When the Joomla SEF option is activated the link targets the same page it's on. Don't know where that comes from since it's using JRoute like any normal extension.
One very cool feature is the possibility to add multiple images to a project. we also have two suggestions. Having a script to resize images to the thumbnail size and a project case study view would be awesome. But those are just luxuries. In conclusion we do recommend this extension and thank the developer for the time and effort put into it.
