DPI stands for dots per inch and is commonly used when referring to image resolution while viewing images on a computer. This term is a bit of a misconception, since digital images are not generated with dots but with pixels. In Fireworks CS5, a graphic design software developed by Adobe, DPI settings for images can be adjusted to fit whatever the user's needs may be.
Open the Adobe Fireworks application on the computer.
Open an image file by clicking the "File" tab on the top left of the Fireworks window. On the drop-down menu, click "Open" and browse to the file location of the image. In the dialogue box that appears, either click the image to highlight it and click the "Open" button or double-click the image file.
Click the "Modify" tab at the top of the window. In the drop-down menu, click "Canvas" followed by "Image Size."
Click the box next to "Resolution." Type the desired DPI setting for the image. For example, 72 DPI is a common setting for images that will be published on the Internet, while 300 DPI is the standard when printing an image. Click the drop-down button in the next box to change the units of measurement to "DPI."
Click the "OK" button to apply the new settings.
