No strip image metadata works for PNG but not JPG

This new feature is also not compatible with disabling strip image metadata . So you will want to disable this new feature if you want to preserve images EXIF.

We have a system where we can prevent contradictory settings from being toggled. Will leave this bug open so we can address this.
