animated GIF
Definition
A graphic in the GIF89a file format that creates the effect of animation by rotating through a series of static images.
Information
Animated banners are made up of a series of frames. An individual display time
is set for each frame, measured in fractions of a second.
A loop is a complete cycle through all of the images in an animated sequence.
An animated GIF can be set to loop once, infinitely, or somewhere in between. Some
publishers have limits restricting the number of times an advertiser's banner
is allowed to loop.
GIF89a is the most common format for animated banners and buttons. Animated
GIFs are relatively easy to work with and widely supported by Web browsers, although
they lack some of the functionality offered by rich media.
The opposite of an animated banner is a static banner.
