Abstract
A method and computer product for inserting additional frames into a “.GIF” file or modifying existing frames that can only be visible by recipients of the “.GIF” file satisfying a certain criteria are provided. A proprietary applications extension for “.GIF” file format allows for playing different images sequences within the same “.GIF” file to a recipient using a proprietary viewer application. The proprietary viewer application extension for “.GIF” file format allows for playing different image sequences in the “.GIF” viewer. A frame modification extension module contains sequence of images (in a binary form) and identifications that the proprietary “.GIF” viewer (with special extension logic) can substitute some of the “GIF's” image data while playing the file. Thus, the “.GIF” viewer is able to play different images (i.e., hidden embedded frames) than the ones played by a standard “.GIF” viewer to a certain recipient.
