Badges can be simple or snazzy, a few minutes fiddling on Adobe Elements or Techsmith SnagIt can produce something simple (which is what you want so other people can use it), the real trick is getting the code for your blog that makes the script that makes the badge code grabbable. Like this:

<div align="center"><a href="http://amindwandering.blogspot.com" title="Perpetual Chaos of a Wandering Mind"><img src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjx1KDiiuSRZTQQEB3BJHsRnWaWZ-JD6nCg6m0y1jHn6BeJn7VDE44TPQah-PN1JIJKizN5gBD4mtZOG91R5xlhXejfGEuCQoS4nyEMLiCqvTTS2ofvE0wXmIIoPwetaWPTM_oUNmeGvsnE/s170/badge170.png" alt="Perpetual Chaos of a Wandering Mind" style="border:none;" /></a></div>
Without that spiffy little window of code that bloggers can cut and paste, you've got nothin'. I can produce the code in the window, but danged if I can figure out how to make the window, but, lucky me! I found a site that does it for you for free.
