Once you're happy with the RotaFota in the preview, you can
save the result as a webpage. Before saving, choose whether the
photos are to be stored as JPGs or PNGs. JPG will produce a smaller
file size than PNG, however it will result in reduced quality in
the final images compared to PNG.
To save, click on the 'Save As' button and choose a filename. This
will create a Javascript file and a subfolder next to the file you
just picked containing the RotaFota images.
