Animated GIFs (something like a short movie with fewer frames) have become popular recently, as an alternative to a brief movie clip.
GIFs have poor compression compared to JPGs, and far fewer colors than JPGs or PNGs. The advantage they do have is animation, a capability that neither JPGs nor PNGs have.
The relatively poor compression means that a feature length movie would be much larger than the other movie formats available, but for very short clips they are OK. The main thing to remember is that an animated GIF will be a lot larger (probably 10 times or more) and probably lower quality than a still image the same size.
We do not recommend animated GIFs unless you have a very good reason to use them. But we can create them if necessary. A bad example is on the left. Do you really want to give people the idea we have a shark problem in Belize? By contrast, a good example of a use for an animated GIF would be to demonstrate a simple action. We have few, if any, websites that really need them. Here is a great example (click on the image to the right to see the action). For more information about this image click here.
They can also make things flashy, drawing attention to something. This has the drawback of distracting from the rest of that web page.
Here are two examples we have recently done (at the top of the page):
