FAQ: Converting GIF or JPG to PNG - The GIF format for images is very popular. Nearly every graphics program supports it. However, there are several problems with GIF (Gif rhymes with Jiffy peanut butter.) GIF was born in the days of very slow modems. To make the images smaller, GIF allowed only 256 colors. This is okay for icons. But GIF is useless for photos. When you convert a photograph into a GIF, quite a bit of the image is lost.

A Few Scanning Tips - PNG - Portable Network Graphics and scanning
GIF, JPEG or PNG? - Here are some file formats you may have seen before. They have one thing in common: they don't belong on the Web. Before we go into these "leftover" formats, let's summarize why the three formats we've talked about so far are good to use on the Web.
Advantages of PNG - Most of us have heard about PNG by now, but few developers are using it on the Web due to the uneven support within the various Web browsers. The format was developed as a result of the Unisys/GIF controversy and the need to overcome the limitations of both the GIF and JPEG formats. Macromedia has adopted PNG as the native format for its Fireworks product, yet most users are still converting images for the Web to GIF and JPEG.
File Types and Optimization - This lesson is designed to help you understand file types and file optimization. In this lesson, you will learn about GIF, JPG and PNG file formats. This lesson uses Adobe's "Save for Web" feature, located in Illustrator and Photoshop. Adobe ImageReady offers the same features, but is set up a little differently. It is recommended that you attend the class lectures to get the full understanding of this lesson.

Image File Formats - Choosing the right file format to save your images in is of vital importance. There are three image formats in constant use on the net — GIF, JPG and PNG. Each is suited to a specific type of image, and matching your image to the correct format should result in a small, fast-loading graphic. Saving and exporting into these formats will require a decent image editor.
