The Use of Tiny Invisible GIF Files

But it is easier just to copy mine. Please do take a copy; please do not use a link to this site. Such a link would work, but it would slow things down, and impose an unnecessary load on this web server. This GIF file is not copyright, so you can do what you like with it.
It has a single, transparent, pixel. Its size is 43 bytes.
