If you had a slow connection, you would notice that at first the image would be blocky and unclear.  As the image keeps loading, the image will become clearer.

File size: 7K

This is showing taking the image with a original color depth of 256 colors and reducing it down to 4 colors, the file size became much smaller and the image quality did not degrade much.

File size: 22K

The JPEG format is not recommended for line and cartoon art.  Notice that the .jpg file size is much larger that a .gif file size.

soccer logo
File name: soccerjpg80.jpg
File size: 8K

The JPEG format is not recommended for line and cartoon art.  Notice that I had to use a compression factor of 80 in JPEG format to get the file size down to a comparable GIF file size.  Notice the poor quality of the image.
