EXIF Data Privacy Warning

When you crop an image, maybe to exclude parts of the photo you want to keep private, make sure the embedded EXIF thumbnail image is updated/replaced when the image is saved.

Unfortunately, the failure to replace the thumbnail may allow the viewing of the original thumbnail image, uncropped, using readily available tools. For example, Android OS phones using Gmail may automatically display the preview of the uncropped original EXIF thumbnail.

This is a privacy/security issue, as the EXIF data may also contain GPS location info.
