On my homepage I was told I needed to have some imagery but I was unsure on how to go about achieving this. I decided to have something called a spacegallery.

Spacegallery uses Jquery to make your images come through each other as you click on them (like a slideshow).
It was quite difficult and problematic to implement but eventually I managed to fix the issues it created.
Another piece of Javascript I used was Lightbox 2.0. This is used for images and makes an image enlarge (usually a thumbnail is used to click on).

It was fairly easy to implement. Simply consists copying files and updating paths.
