Most of that information is innocuous. Camera shutter speed and aperture setting. There is no significant future threat to that information. But what if you use a GPS device to locate the location of your photos? It must be helpful, but you certainly won't want to upload your own backyard GPS location to the web.
And then there are also keywords and tags. If you use a way to tag photos of your friends, relatives or colleagues with a nickname, for example, don't forget that if you upload it on a shared website, the tag content will come with it. That's why anyone who sees these photos will see that information.
Protect your privacy
If you don't want to share private information with the whole world, there's a way to get rid of all your personal information from your image files before uploading them to the Internet.
You can remove all the photos included with Windows itself if you are using Windows Vista. Just go to the Details tab in the Properties dialog box. At the bottom of the window, you will see a link to Remove Properties and Personal Information. Click on this link and all data attached to your photo will be removed from the image. You can even select a few photos and perform a split operation simultaneously.
If you are not using Windows Vista, or you want to find an easier way to remove data, try using the JPEG & PNG Stripper program. This free utility can do exactly what it promises: To use it, simply drag your image files into the Stripper window, then the data attached to the image will be deleted immediately. .
You may want to remove the data with the image only in the copy you want to upload or share it. If you use both methods to delete data, it will be lost forever. Do not perform with the original image file if you want to keep that information included on your computer, but only do it with the copy.
