How to make an animated gif (easy way)

downloads.com.

To start you need to open any paint type program and draw all your pictures. Save them in some kind of sequence like the examples below.
- For the Web I saved these as .gif files, but most paint programs save the files as .bmp bitmap files. Web browsers don't like to show .bmp files, but that's OK because most animated gif programs such as Animagic will convert your bitmap files (.bmp) to .gif's.

face1.gif	face2.gif	face3.gif	face4.gif
Now import your frames like the four above into your Animagic type software and the software will put the pictures together into one file such as the one below.

I use Animagic for my animated gifs, but there are many other choices out there. Make sure you know what Animagic is used for on a quiz of final.
