Colorized theme comes with a nice looking sponsors widget. However, you will need to set it up in order to use.
- Prepare either 80X25 or 80X80 images for all your sponsors.
- Go to Appearance > Widget and select Colorized Sponsors.
- Now you can have either small type or big type sponsors.
- For small type use 80X25 images.
- For big type use 80X80 images.
- All images will line up automatically inside the widget.
Place the widget inside your footer and you are good to go.
