I've got a web question.  Some websites - at least in the version internet
explorer I'm using - at the left of the address line at the top of the
window and in the label on the tab in IE, show a little "logo."  Presumably
they have something or other to do with the website's content, and sometimes
they are kind of cute.

I'd been wondering how they got there - I figured it was somehow part of the
title you can give a web page in html, that you put in a link to a graphic
as well as the text of the title.

Then I went to read something old on my own site, and there was such a logo.
Reasonable-looking, too.  I didn't put it there, that's for sure!

Does anyone know where they come from?
