It will be important for you to reduce the file space needed for images
you might use in your web pages or in your applications, such as Power
Point. It is important for 2 reasons: a)You are limited in
the space you are allotted on GAC's server, and b) you want the web
pages to load as quickly as possible - especially if someone is using a
28k modem. The photo you just downloaded is about 448k, much too
big for our purposes.
In Photoshop, there are several things you can do to reduce the image
file size:
1. First, crop the picture. The "cropping" tool is in the upper left corner of the Tools window. Try cropping the above image in Photoshop - e.g., get rid of the tail and lower body of the dinosaur.
2. Next, reduce the image size. Click Image>Image Size to reduce the size of the image to approximately 3 inches in width.
3. Then, reduce the quality of the image. Click File>Save for Web. Choose the "4Up" palette and the JPEG setting. Try the "Optimized" palette. How small have you made the file? Will it still look good on the Web?
4. You could also reduce the number of colors in the image. Try the Gif setting instead of the JPEG setting. Vary the number of colors using the pull-down menu for "Colors". How do the Gif file sizes compare to the JPEG file sizes? How do they compare in quality?
5. Choose one reduced-size (12 kb or less) image file to save. Pick the one you think is still of satisfactory quality, but also has a small file size. Save it locally (HD>Shared>Users). Use your last name for the file name and end it with .jpg or .gif - depending on what format you have selected.
6. Finally, drag your reduced dinosaur to the dinosaur folder in xServe.
