Many authors choose to include higher-resolution and/or color versions of images found in their electronic documents.
The preferred format for images is TIFF, JPEG and GIF. As JPEG and GIF typically utilize lossy compression algorithms, TIFF images will have better image quality.
LZW compression in TIFF images is acceptable, but please make a note in the accompanying "readme.ed" file that the images are LZW-compressed. The images will be converted to TIFF format without LZW compression before they are placed on the CD-ROM.
