Replace a photo within an album. To avoid re-entering the description or other information such as location or title, you can replace a photo with a newer version by going to "Tools" >> "Edit Photo" . This will display the photo tools among which you can find also the button to replace your photo.
Keep the settings, data, and comments. After you have chosen this option, you may upload a photo that the current photo will be replaced with - all of the information assigned to the original photo (including the comments, et cetera) will be used for the new picture as well. If the replaced photo was used as a cover for your category, the new one will be automatically used instead.
