I hope this short article has been helpful and interesting to those who didn't know much about JPG compression before reading. If your website is based heavily around JPG images which aren't yet compressed, you should be able to halve your bandwidth usage per month, at least. Remember though, there are also a cavalcade of GIF optimization programs out there if your website has a focus on GIF images more so than JPG, a Google search proves this.
I didn't set out to put hosting companies out of business by posting this article, but the facts are simple - with the way the advertising dollar is right now, us webmasters need to do everything possible to cut back on costs while maintaining quality websites, and in this case, image quality.
If you have any comments or other suggestions about saving bandwidth, please leave your comments in our Application & Web Development forum.
