Start Photoshop on the Macintosh Computer that is next to the scanner. To do this, click on the apple icon in the upper left hand corner of the screen, choose Applications->Adobe Photoshop 5.5->Adobe Photoshop 5.5. After Photoshop starts, put the image to be scanned on the scanner bed and choose File->Import->Perfection 600. Hit the "Prescan" button on the Perfection 600 dialog box. You should now have something like this.
Set the resolution as low as possible, while still maintaining a reasonable picture quality. Lower resolution yields a lower quality image, but the image will be smaller. This means it will take up less space on the server, and will also download faster. For comparison, most computer screens are about 72 dots per inch (dpi) and a laser writer is about 600-1200 dpi. Select the area you want to scan, in this case the picture of the CD, and press the "Scan RGB" button.
At this point the image should be in a Photoshop window, and you have two choices for putting it into your web document.
