|What software can I use to create my own theme for use in a quiz?
The Professional version allows you to use any .jpg or.gif file as a background image. You can also use any Flash image/animation (up to Flash version 8) as a background.
You can set this up as part of the quiz properties, in Appearance Settings - Override Background Images. You will see a section called Override Background Images where you can change the background image of the quiz, the loader or the finish screen by browsing for and selecting the file name of your image.
You can use Photoshop or Paintshop to create the images and Flash Studio to create Flash files. See also Background Image for more information about the images you can use.
Question Writer also provides a commercial custom theme creation service. There are more details here http://www.questionwriter.com/pricing/custom-development.html
