Here is the information you asked me about. Log in to Blogger by clicking on the orange icon on the upper left corner. Write the username and password (if using old version) or gmail address and password (if using updated new version) . Go to the section "edit my profile" on the right and in the area where it says "photo URL", paste this code:
Don´t forget to click on "save" at the very end of the page to save and update your profile.
I also even opened a site for you. There you will see your photo in the profile section: http://horaciovenezuela.blogspot.com/
Good luck, I hope it works, cariños, Berta
