When taking photos your camera also stores many information with your image file such as camera model, date and time, exposure, aperture, ISO, location of the photo (GPS), what camera mode was used, whether or not a flash fired, and more. Your photos also store information about image editing programs. These data is called Exif (Exchangeable image file) data and you can read it using specific applications.
If you want to extract Exif data from any jpg online photo, for example an image from Flickr, there is a very good online exif metadata viewer called Findexif. Just paste the URL of the photo (no need to upload photos to its server) and click Go button. It will instantly display information (if available).
EXIF data can be useful for a variety of reasons. For example, photographers can compare shots to find out what they did right and wrong in them or you can identify whether the photo is original or photoshoped, etc.
If for some reasons, you don’t want to disclose EXIF data of your image, you need to make sure that no such information is saved within the picture files. There are several applications available for removing exif metadata from image files (see example here).
