You can also have two (or more) images alternate.
Just make your source a multiple of a square, like 50x100 (for two) or 50x150 (for three). Each source image must be in a square, and only the image contained within the largest circle that fits that square will get rotated...
Note that the cell size is that of each square, the number of cells is the total (2 x 12 rotations), and it has two dimensions. The first dimension has 2 cells and increments (these come from the columns). The second dimension has 12 cells and is angular (this is the rotated row of images).
Refresh brushes and draw with it.
(I toggled on "Use Color from Gradient" with a rainbow gradient selected in the paint tool dialog in the lower half.)
