From the first screen - to enter a category, select one of the small pictures (thumbnails)

Once in a category, you can browse through the pictures by either:
1. using the thumbnails to the right of the main picture;
2. using the arrows on either side of the main picutre;
3. or by using the autoplay mode in the controls underneath the thumbnails on the right.
(You can change the speed of the autoplay by changing the number next to the controls - the higher the number the slower the pictures will change.)

To change to another category - use the two small buttons at the top of the thumbnails:
The down arrow will show the full menu allowing you to jump straight toanother category, whilst the other arrow will return you to the main page.
