Theme Sites. These are of course thematic, which will be helpful on what theme you want to use in a page. Scrapbooking is like Wordpress. If you are making a website powered by Wordpress, you will look for nice themes that you can work on instead creating your own. It should be appropriate in the long run as you post and update it. In scrapbooking, templates will stick for a long time after some time of adding all the elements, and it will be the basis of the overall look that you can't change. Photo Sharing Sites. These sites are both theme and group sites at the same time. Photo sharing is mostly their goal, but I have seen scrappers post their layouts or projects. So you will get templates or their ideas as well.
What is the initial process and how do you get your hands on WordPress in order to create your own website templates? You will need to go to WordPress.org and download a version in the language of your choice. You then extract the zip folder into the root of your site, and you will see tons of files pop up. Don't worry about opening those or going into them as what you need to work with will be significantly small. Then go to yoursite.com/wp_admin/ and you will go through the simple installation process which is basically just WordPress hooking itself up to a database which it creates in your server in order to work. That's all there is then you can start rolling.
