Types of Images On Web Pages- Kelly Moran

The three most common types of images on web pages are GIF, JPEG, and PNG. The Graphics Interchange Format (GIF) is a bitmap image format that supports up to 8 bits per pixel (Wikipedia, 2011). The Joint Photographic Experts Group (JPEG) is a graphic image format that supports up to 24 bits per pixel (Wikipedia, 2011). Portable Network Graphics (PNG) is a bitmapped image that supports up to 64 bits per pixel (Wikipedia, 2011).

For photo images and graphics, a PNG file will have the best quality (Fulton, 2010). If file size is an issue, a JPG photo file will have a high quality, but not as good as a PNG file. A JPG file would be the least desirable choice for a graphic file, because when compressed it can smear text and lines. A GIF file would be the least desirable file choice for a photo because of the limited color, but can be used for simple images including graphics or logos of solid area color. JPG and GIF files do, however, have the maximum capability with PC, MAC, and UNIX.
