Editing your photos in the Gallery
The Gallery program allows you to resize your photos and to rotate them by 90 degrees in either direction.
To edit a photo, click on that particular photo so that you get the large view and then look at the options on the left for the ‘Edit Photo’ link. A page with tabs at the top will appear. Tick the box at the bottom that says ‘Preserve Original Photo’, just to be on the safe side.
To rotate the photo, choose the ‘Modify Photo’ tab, and then under ‘Rotate’ choose either C90 (clockwise), CC 90 (anticlockwise) or 180 (rotate to the other way up).
