This plug-in is similar to the previous one, Image Display, but it saves the new image to disk. Wrapped in suitable code it's very handy for automatically changing image type (and quality) either singly or in batches.

The Figure shows a 42Kb JPEG image which has been converted to another JPEG of only 8Kb by using a quality setting of 25.

This plug-in converts between JPEG, GIF and PNG and can change quality setting too
