information (such as drop shadows), and all elements are fully

JPEG (Joint Photographic Experts Group) file format is the superior
format for photographic or continuous-tone images, because JPEG
files can contain millions of colors. As the quality of a JPEG file
increases, so does the file size and the file download time. You can
often strike a good balance between the quality of the image and the
file size by compressing a JPEG file.
PNG (Portable Network Group) file format is a patent-free
replacement for GIFs that includes support for indexed-color,
grayscale, and true-color images, and alpha channel support for
transparency. PNG is the native file format of Macromedia Fireworks
MX. PNG files retain all the original layer, vector, color, and
effects information (such as drop shadows), and all elements are
fully editable at all times. Files must have the .png file extension
to be recognized as PNG files by Macromedia Dreamweaver MX. |
