The Show Partner graphics file format is a legacy bitmap image standard developed by Brightbill-Roberts for the Show Partner F/X multimedia software. It was historically employed for creating electronic presentations and slideshows on MS-DOS operating systems during the late 1980s. Because this format is obsolete and lacks support in modern image viewers, accessing its contents typically requires specific conversion utilities or emulation environments, though it presents negligible security threats.
