Hi guys, I would like to know how do I add my own Avatar that will appear on my comments instead of the random one?

You generally just set one one the various services like Gravatar.

Thanks for the response Imilesw... but what i meant is, I am the author of the website and i want an avatar for my self. is there a way to do that on the Atahualpa theme?

It works for the author or visitors. Just go to gravatar.com and create an account. Your avatar will be tied to the email address you use for your user profile.

ok thanks, i will check it out
