Computers store images in several different ways.
Some storage methods focus on compressing the size of the image as much as possible.
A major problem with using images on websites is that images take much longer to load than text.
To reduce download times as much as possible two of the best image compressing formats used on the web are:
|256 colors||Unlimited colors|
|Can handle transparent areas||Can't handle transparent areas|
|This format is not good at compressing photographs||Excellent for compressing photographs and complex images|
|In general, it is excellent for banners, buttons and clipart||In general, it is not good for banners, buttons and clipart.|
This means that:
If you want to use an image that is in a format other than JPG or GIF, you will need to load the image into a graphics program and save it as either JPG or GIF.
- Banners, buttons, dividers, clipart and other simple images usually work best as GIF's.
- Photographs and other complex images usually work best as JPG's.
