Preparing Images for the Web
by Sue Barthelow
I cringe every time I open my inbox to check my e-mail and see a message that has a large attachment. Most Internet users, my friends included, don't know about file sizes and download speeds. They know that some e-mail messages and web pages take longer than others to show up on their computer screens, but they have no idea why. If you don't know how to lower your image sizes, this tutorial is for you.
E-mail recipients need to open attached images fairly quickly, and web users need to download web page images at a reasonable speed. Many people have fast links today and don't notice their download speeds. They tend to forget that others cannot use a fast service to access the Internet. For those unfortunate few, attached images and web pages crawl onto their computer screens.
Mine creep. Several weeks ago, I started to download a friend's e-mail attachment. I got up from my computer, went around the house closing windows, got a cup of coffee and returned to find that I still had to wait. Ouch. I usually just delete messages with large attachments, but I wanted to see this one.
So, help your friends out and think about sizes before you attach an image to a message or upload it to the web. How do you solve the size problem? Use your photo processing software to save your image with the smallest file and quality that leaves you with a good looking picture.
Here's how to do it using your photo software. This example is for Photoshop Elements, but other programs have similar capabilities.
