convert to JPEG in Demo.

I'm curious why this converts to GIF (which is not designed for photos) rather than to JPEG (which is what most people want).

Either JPG should be the default or there should be a pull-down to allow people to select.

Some Heic images contain a burst of images (multiple images) and thus can only be contained in a gif.
