Image Strip Compression
There are a lot of options for reducing the file size of a computer file.
I preferred to preserve the image as image, since .gif itself already uses a compression technique, and the final Adobe Flash animation can cope easily with images.
The GIF file format - Graphics Interchange Format - is based on the
so-called LZW compression technology, patented by Unisys. LZW is the
abbreviation for Abraham Lemple, Jacob Zif and Terry Welch, the
inventors of this technique.
