For the unitiated, the differences between the three file types is as follows:
.bmp These files can contain millions of colours, but are not compressed and so are very large in terms of file size.
.gif These files can contain up to 256 different colours, but they may be animated and have transparent regions. They are smaller files than .bmps of the same dimensions.
.jpg These files can contain millions of colours, do not support transparency or animation. They are compressed, and so are smaller files than .bmps of the same dimensions.
I reccomend using GIFs as these are great for games. JPGs can be used for photorealistic graphics, but are less felxible than GIFs.
To open a .bmp file for editing, right-click on the file, and choose edit from the menu.
It is assumed that you know how to use Microsoft paint to create images.
Before you draw anything, you must first decide how big you want your game objects to be in relation to your game environment.
Once you have planned this, we will use Adobe Fireworks to convert your graphics into your desired format.
For the time being, we will use blocks of colour to represent your game elements.
