Digital pictures save a range of details about the photograph, such as what type of camera was used and the date the picture was taken. This information is called the EXIF data, or Exchangeable Image File. You don't need to download any additional software to can check on the properties of your digital picture as Windows 7 provides viewing and editing capability within the basic operating system. You may need to change some settings or copy the file over to another location if you are having trouble editing the photo properties.
Navigate to the digital photo you want to edit. Right-click on this photo and click "Properties" on the pop-up window.
Check the bottom of the "General" tab next to the "Attributes" section. Make sure the box labeled "Read-only" is not checked. If this box is checked, you will only be able to view the properties and will not be able to edit them. Uncheck the box and click the "Apply" button to save the file settings.

Some details might not allow editing if they have been copyrighted. Type in the new text or select the value from the drop-down menus.
