When and how to use file compression
From within your image editing application, do not compress any graphic files that you plan to import into your page layout. For example, when saving TIFF files in Photoshop, you have the option of applying LZW compression. Leave the box unchecked so no compression is applied.
If you use stand-alone file compression utilities such as StuffIt, PKZip, or WinZip, the resulting compressed files cannot be imported into a page layout. Use these utilities only to compress files for storage, archiving, or sending over the Internet — they will have to be decompressed before they can be used.
