The file format is irrelevant.
If they want to change the photos, and to avoid having two different versions, they probably do it before publishing the images in any format, either
GIF, JPEG, JP2 or IMG.
Professional altering of photos (and not even professional, I have changed a photo and it does not show any signs of tampering) is not noticeable,
regardless of format.
