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.

- In June 2003 Cat Schwartz became the subject of a stir in the Internet community when it was discovered that at least two cropped photographs of herself she had posted on her personal blog contained hidden Exif thumbnail images clearly showing her bared breasts, because the program she used to edit them, Photoshop, did not create replacement thumbnails.
