If you are using ToyBase v6, follow the instructions in the User Guide: If you have a logo for your organisation then scan it as a PNG or JPEG image and save it as logo.png or logo.jpg. Place the file in the folder:
C:\Program Files\Toy Library Database\My Toy Library\
The logo will appear on the welcome screen. If you are using ToyBase v7 the location of the logo has changed but the instructions are out-of-date - the image must be a .png file and it's location is now:
    C:\Program Files\devstopfix.net\ToyBase7\Images\toybase(smaller).png
Replace this file with your logo file.
