Hi,
In this post i will learn you how to create a fullscreen portfolio with thumbs as in:
http://theme-dutch.com/presents/jamesHarrison/category/black-and-white/
It's really quite easy to achieve this effect.
1: Intro) Keeping in mind WordPress is a blogging system by default and alot of users are used to creating category's and posts we build this portfolio type on posts.
2) You will have to create a category and give it an appropriate name
3) Next up you will have to fill it with some posts (don't forgett to give each post a featured image, this will be used as image)
4) Now that's done you will have to visit the James panel and check the "category setup" tab.
5) Set the category you created to gallery.
6) Now insert the category in your menu trough the WordPress menu's and you're done.
Regards,
Chris
