Can someone please explain to me the difference between a portfolio and a gallery.
In the online sample (http://www.kriesi.at/themes/flashlight/portfolio/), portfolios seem to lead to galleries, I'm not sure how this is done! In the training tutorials you create a gallery in a WordPress Page, but Portfolios have their own area and categories, etc...
Here is what I want to achieve. I would like a page similar to the sample portfolio page above which has a key photo for each of a number of categories (travel, people, pets, kids, house, etc...). When you click on the image or title, it could take you to a gallery page or, if there are sub-categories, it would take you to another portfolio page, with another series of categories. So, if you clicked on Travel, you would go to another portfolio page with a number of Travel sub-categories (europe, north america, australasia, southeast asia, south america, etc...), and potentially, each of those categories could have sub-categories (north america -> canada, usa, mexico) until you are eventually taken to the final category and it's gallery page.
Can you explain how to do this?
