Photo Detagger - Protect your jpg privacy!
 Unknown to many people, photos taken with camera phones often contain hidden information about the image and its creator, so called metadata tags. These tags are written to the files by digital cameras and photo editing software.
There are many different tags, such as Exif, IPTC, XMP & Comments. Although mostly a useful compliment to the picture, there are many reasons why you would want to remove these tags before publishing an image.
These information (or 'tags') can be used by the receivers / viewers of the photos (e.g. on Flickr or other photo-sharing websites) to index & profile the photographs and (indirectly) the photograhers themselves based on these embedded information (technically known as EXIF data). In newer phones these information can include GPS satellite locations, revealing both the exact time and place where the photos were taken.
With Tea Vui Huang's Photo Detagger on your mobile phone, you can now detag and wipe out all these tags from your photos before sending them out or posting it on the Internet! Previously, the only other way to do this on the phone was to use the phone's photo editor to alter and resave the file, reducing the quality of the photo in the process. Photo Detagger removes the tags without damaging the photos and in the process even reduces the size of the JPEG photos by about 3-5 KBytes as well.
The detagged photos will be saved to the "Images" folder of the microSD card with a "-001" suffix. You can then send out the detagged photos via MMS or upload it as per normal to your preferred photo-sharing websites or blog. Photo Detagger is designed for Nokia phones minimally supporting CLDC 1.0, MIDP 2.0 and JSR 75.
