In the file default.msl that you can find in the images directory under your TB program directory. When you prefer to have the pictures next to the signs, use the Quick Template (QT) that I post at the bottom of this reply. Save the QT with the name DShow, this name is important as it calls itself recursively.
After you've saved the QT (Options -> Quick Templates)
This QT is written by Robin Anson and posted to the TheBatUserDiscussionList (tbudl@thebat.dutaint.com)
Here's the QT, just copy (Ctrl-C) it and paste (Ctrl-V) it to the QT edit screen (don't copy blank lines):
