If you want a watermark that fits different size objects then use
the scaling option. Click on the configure button and then for text
1. Click on the "Scale to Full image" box and select the amount to
scale to the image. Before this option was added the watermark might
be just right on a small image, but teeny tiny on a large image.
Note: You can still use the font size to change how large or small
the text is even with the scale option.
