Mail app question

Hello everyone,

I use my Gmail a lot for a lot of very important e-mail correspondence. Unfortunately for me I've been playing around with Photo Booth app yesterday and sent out attachments with "funny" faces to some friends using that Gmail account. Now when I send any e-mail either to myself or someone else one of these pictures appear at the top right of the message in the Mail app. I turned off Gmail settings to "No Picture" for my e-mail account but the problem is still there.

What should I do? Please help!

 

Problem solved.

Somehow my user account picture was changed to the one that kept sending out. I just changed it to what I had before and problem went away.
