The Picture perfect theme does not automatically put the photos n the sliders. You need to do it manually.
1. Download Picture Perfect theme.
2.In the Wordpress-Admin-Pages menu, create 7 pages that will be your seven headings in the menu. They can be a real pages with content (Eg 'About me') or you can go down the bottom of the page entry and select the 'page links to' and link to anywhere else like this:
3. If you'd like to change the images, you need to use an FTP program to upload new jpgs to override the existing ones in the wp-content/themes/slidingsdoor/imagemenu/images directory. They need to have the same name, and be 320x200 in size or it won't work.
I'll try to say this again as some people are not getting it.
The 7 pictures in the image directory connect to the first 7 pages. These pages don't yet exist (you cant provide pages with a theme). The current sliders are just pointing to random stuff. So you need to make your own 7 pages. This is the first step. When you have made 7 pages, the 7 sliders will now point to your pages.
Picture 1 connects to Page 1
Picture 2 connects to Page 2
Picture 3 connects to Page 3 and so on.
So just create some pages and put in them what you want.
The 'Page links to' entry down the bottom is for if you want Picture 1 to point somewhere other than Page 1.
You can point point picture 1 anywhere via the page links to field of page 1, and then picture 1 will go wherever that URL tells it to go.
