The next stage after making text only exercises is to add some graphics.

We presently have one exercise - Memory - that has text and graphics.

There are 2 important rules for using graphics:

1. The graphics must be saved as jpg.
2. The graphics should preferably be saved at 130 x 130 pixels.

You can save the pictures at greater or lesser sizes - they will be resized. But this may affect the quality of the picture.

Neither is it absolutely necessary for the pictures to be square. But again, this might affect the quality of the result. You are welcome to experiment and see what suits your requirements best.
