There are plugins to do this, but I beg you to reconsider. Captchas do not stop spam. Spammers mostly use trackbacks, bypassing your comments form.
All captchas really do is prevent people who are vision impaired from posting.
If you want to stop spam, use these plugins:
-Bad Behavior
-Akismet
-Spam Karma 2
These are proven, effective methods of stopping spam. Bad Behavior + Akismet is my preferred choice. These stop 99.999% of spam on the various blogs I run.

Ok, the image thing worked very well for my wife, but I will try something else. After all, you did beg.
I’ve clicked on “activate” in the row that is for Akismet under the Plugins section. Now I have to get my key.
I clicked “Get your key” and was taken to a blank page.
I check my profile in my wordpress blog and couldn’t see it.
I checked my profile here in these forums and couldn’t see it.
Where is this key?
Go to WordPress.com and sign up for an account there. You don’t have to use the free blog that site gives you, but the API key will be in your dashboard on that free blog.

It says my user name (which is very unique) already exists. I will try creating a new one.

Ok, it says it’s activated. What happens when that user account that I made become inactive? (I have no intention of remembering the user/pass for it, let alone using it.)
To the best of my knowledge, they don’t deactivate accounts on wordpress.com for inactivity.
