When you want to have a photo moved, go to the current location of the photo, click on the photo to enlarge it, scroll down to the list of "Actions," and click on "Move this image to another plant." You will then be asked for the name of the new plant. Enter the name, click "Search," choose the correct result from the list of options presented, and submit the proposal to move the plant. The proposal will have to be approved by a moderator or administrator before it goes into effect.
