PNG stands for portable network graphics. It is the raster graphics format associated with the .png filename extension. Unlike GIF format, the limitation of 256 colors does not hold with the PNG format. In fact this among other reasons was the motivation behind development of the PNG format to improve upon the GIF format. The PNG format however uses a single image format and thus does not support animations. Because the format was engineered to ease the distribution of graphic files across computer networks it is also not well suited for professional graphics.
CMX stands for Corel Metafile Exchange Image File, it was a proprietary file format designed and used by the famous software company Corel Corporation.

The CMX file not only contained the image but the data within the image which allowed stored information to be communicated between different software that could read that information.
