We have had to log in via FTP to Clean Up (delete) images that were either incorrect or just didn't belong in the Volusion "Photos directory".

All the problematic images had the extensions: "-2S", "-2t_mobile" and "-2t_mobile_zoom". For these images, the product was either deleted and these images remained and did not get automatically removed when the product was deleted, OR we uploaded a different product photo and the images with the above named extensions did not take on the new image.

This is a problem if Volusion serves up one of those images!
