I'm stupid, I make no excuses about that. I looked and looked, then looked some more. Finally I used the best resource I know of for WindowBlinds. The Masters. So here is a quick post on how to turn off that silly user pic in 10 easy steps.
1. Open SKS
2. Click "Open Skin"
3. Nav to the skin you want and click on "Edit Skin"
4. Select the substyle you want to change if it has one
5. Click on "Edit Start Menu and Taskbar"
6. Select "Edit Start Menu"
7. With "Top Part" selected, click on the "Extra" tab
8. Scoll down to and select "Hide the user picture" and check the box to the right that says "Enabled"
9. Close the "Edit Start Menu" window
10. On the tool bar, select "File" and click "Save skin", then click on "Apply skin" and you're done. No more cruddy user pic.
The Masters know, and now you do also.
