User Picture Tuner is a small application that allows you to change several interesting features of the User Account Picture in the Windows 7 Start Menu. You can customize the behavior and appearance of the user picture aka "avatar" and it's frame.
There are several option available, such as:
Change transition animations between icons in Start Menu. You'll able to change:
delay before the animation start;
fade out delay - how long it takes for the new icon to replace the old one;
fade in delay - how long it takes for the new icon to fade out from the view.
You can completely disable transition animations. Use the small link "Disable all animations".
Change the user picture frame. You can replace the default frame around your avatar with a custom image. Sure, you can restore the default user frame by clicking the "Restore" button.
Windows Explorer restarts after you apply changes. Note that you need Administrator's rights to change the user account picture frame.
