You can just google log in and it will give you a forum clipboard to copy and paste here. And how can it be modified, I wonder.
Seems the way image links are coded changed, it used to be an number on the URL now it's letters as I see.
Your result:

DB < 105

http://img.10fastfingers.com/badge/1_wpm_score_DC.png
DC < 106

http://img.10fastfingers.com/badge/1_wpm_score_DD.png
DD < 107
What I am trying to say is, because you got 105 result, doesn't mean it's a special MD5 Hash code or something, it's just site-generated images with standard URL based on result
