Is your avatar (your commenter photo/image) on Giza a pre-determined cartoon? That can feel like life, sometimes, but it doesn't have to be that way - at least on Giza. To customize your appearance as a commenter, visit gravatar.com and set up or update a gravatar account associated with the **same e-mail address** you’ve used as a member. Gravatar lets you associate a photo or image with your account to be used on any site where you comment with that same e-mail address. Keep in mind, we can’t support issues with gravatar.com, but that’s how it’s done. If the e-mail addresses match, you should see an updated avatar after a few minutes. If not, give it a day. The cache updates periodically.
If you're unsure of the e-mail address associated with your Giza account, or need to change it: See the Member Options page, and Modify Member Profile.
