Go to your pictures. Select the one you want to work on. On the top will be boxes. The second box from the right will have "Properties" and some greyed out items. Select the "properties" then push edit. The 2nd box from the left will have "Crop/ Resize etc. Pick the one you want and it will crop/rotate/resize, et.al. I know this sounds like alot of steps but it really is easy once you do it a couple of times.
