Also, I'd like to understand the ramifications of using different
compressions for jpegs. I understand that it controls file size, and
thus the download time, is that right? Is there more? My little (and

them save them at the maximum compression quality?
When you compress using JPEG, the image is degraded in quality. The JPEG
format always reduces image quality; it makes the file smaller on disk
by removing information from it and degrading its quality. JPEG was a
file format invented for use in situations, such as the Web, where file
size is critical and image quality is not important.
When you set the image quality in a JPEG, what you're doing is telling
the computer how much to degrade the image. The more you degrade the
image, the more artifacts (such as blurring and banding) you see, and
the smaller the file is on disk.
