The 2006 edition of Problem Pictures Themes CD-ROM has 300 colour photographs with activities for mathematics teaching.

Themes covered include Chocolate, Games & Puzzles, Mazes, Perspective, Time, and Wheels, as well as a large Medley section covering many other topics. U-Shaped Curves, Straight Lines & Gradients and Waves & Other Curves are three sections that can be used to model photographs with graphs.

Like the original Problem Pictures CD-ROM, this disc contains a varied collection of attractive and unusual images which are starting points for mathematical activities. This disc is intended mostly for students in the 9 to 16 age group, although some of the activities will appeal to younger and older students.

Each photograph is saved as jpeg files at four resolutions, the largest being 1365 x 1024. The text can be copied and pasted into other applications. The 2006 edition includes hints and solutions.
