The well known PNG format is APNG it has got many features, it supports for animation and in additional to it has got 24 bit images, and eight bit transparency, the ordinary frames with two additional data chunks is contained in an APNG file, for all APNG data there are certain rules, they are in glance the size of the total APNG is the size of the first frame, an aCLT chunk must appear before any IDAT chunks and fCLT chunk must appear before the IDAT chunks. Before the entire image is read APNG is designed to allow incremental display of
"APNG is designed to allow incremental display of frames before the entire image has been read. This implies that some errors may not be detected until partway through the animation. It is strongly recommended that when any error is encountered decoders should discard all subsequent frames, stop the animation, and revert to displaying the default image. A decoder which detects an error before the animation has started should display the default image. An error message may be displayed to the user if appropriate.

"If you've always wanted to create animated images from scratch, there are now simple ways to learn how even if you're not a professional cartoonist. Animations work similar to cartoons because you must create a variety of images that are very similar, but different in just a small way. As the images are "flipped" or looped on the computer screen the animation comes to life.
Free animated gifs are available online, but sometimes you might need to create your own. For example, you might want to create a holiday special animation for your website to
My wife is a tenderfoot in the Web development arena. Imagine how surprised I was when, after just earning her certificate in Web design, she sprung this revelation on me: "HTML is going to be replaced by SMIL." I thought, "Who do you think you're talking to, sister?"
I reckon I was most put off because I wasn't sure I knew exactly what SMIL was.
Structured Multimedia Integration Language (SMIL) is to multimedia developers what HTML is to linked-content developers. I remember reading about SMIL a few years back, but I recall thinking that it
SMIL known as Synchronized Multimedia Integration Language is used for time based delivery of multimedia content over web. It is possible to mix different multimedia elements such as text, video, graphics, audio, and vector based animation and synchronizes them to a timeline for delivery. SMIL is a World Wide Web Consortium recommendation.
Using SMIL a user can describe the behavior of the presentation, describe the layout of the presentation and associate the media objects in the presentation with hyperlinks. Basically SMIL is a XML document with
Synchronized Multimedia Integration Language 2.0 (SMIL 2.0) is an XML-based language that allows authors to describe the temporal behavior of a multimedia presentation, associate hyperlinks with media objects and describe the layout of the presentation on a screen.
Rather than being formulated as a standalone multimedia vocabulary (like SMIL 1.0), SMIL 2.0 syntax and semantics may be reused in other XML-based languages, as when SMIL components are used for integrating timing into eXstensible HyperText Markup Language (XHTML) or Scalable Vector
