I’m trying to figure out a way to create a zero-width, zero-height image which would conform to the standard of whichever format works.

I’ve already tried the Windows Bitmap (BMP) format (54-byte header only file), but it appears that image readers will not accept it.

Theoretical 0x0-BMP byte string:

424D360000000000000036000000280000000000000000000000010020000000000000000000C40E0000C40E00000000000000000000

Which format would support this, and which tools can I use to create it? Even a programming solution would suffice (e.g. a C# System.Drawing script).

    Image readers will tend not to accept a width of less than 1 or a height of less than 1. Hence we need to stay with 1×1 as the minimum that can be practically used, even if 0x0 is allowed by the specs of some image formats. A 67-byte PNG is detailed at http://garethrees.org/2007/11/14/pngcrush/ perhaps the smallest possible. A transparent one can be done in 67 bytes also.
