in case you were wondering

The smallest valid GIF image can be generated with the following command: 

/usr/bin/printf
    "GIF87a\x1\x0\x1\x0\x80\x0\x0\xff\xff\xff\xff\xff\xff\x2c\x0\x0\x0\x0\x1\x0\x1\x0\x0\x2\x2\x44\x1\x0\x3b"
Correction:

Jim correctly points out that you don't actually need a color table. Moreover, only one byte of image data is actually necessary. Thus, 

/usr/bin/printf "GIF87a\x1\x0\x1\x0\x0\x0\x0\x2c\x0\x0\x0\x0\x1\x0\x1\x0\x0\x1\x1\x0\x0\x3b"
