GIFEXE
From Just Solve the File Format Problem
GIFEXE is a DOS utility that converts a GIF image file to an EXE file that, when executed, displays the image. It was developed by Steve Enns, Dan Magosse, and Synergrafix Consulting.
Format details
The viewer part of a GIFEXE EXE file is compressed with LZEXE. The overlay segment (refer to MS-DOS EXE#Special file positions) contains the original GIF file, followed by a trailer.
Identification
Files made by v1.0, v1.2, or v2.0 end with ASCII "GIFEXE".
Files made by v3.0-4.5 end with these 8 bytes: ASCII "GIFEXE3", then byte 0x00.
