 Thumbnails are used to show a library of images in a small space.  When you click on the thumbnail image the full size image appears.

 A new application by Microsoft is in development called Pivot which allows people to sort through data using images as a medium.  It uses thumbnail libraries to help convey information.

 When you click on an area you are presented with thumbnails.  Click on a thumbnail and you are taken to a website (or websites) related to that image.  The more thumbnails you have though, the longer it takes to download them all.

 List the advantages and disadvantages of using a collection of thumbnail images.

 There are different types of image that you can work with.  Bitmaps and Vector are two types which you need to learn about.  Both have their advantages and disadvantages which make them suitable for different things…but in order for you to understand those you need to understand what makes them different.

 Describe the difference between a bitmap image and a vector image.  Create a table which compares vector images to bitmap images. Each entry for vector should have a comparative statement next to it. For example:

 Explain why a bitmap image is more suitable for photographs compared to a vector image.  Giving reasons, explain why an architect would be better off using vector images when he create blueprints for his next house design.
