Rotating, Cropping and Resizing Images
Cropping, Rotating or Resizing an Image is Quick and Easy
When you upload an image to the Media Library, by default your image is saved to a small thumbnail, a medium size, and a large size, based on the settings in Settings > Media in the left admin menu. Once uploaded, you may edit the image using the system’s built-in image editing suite. In the Media Library simply click Edit by the image you want to edit, then you will see a Edit Image button on the page that follows. Once clicked the editing suite pops up and gives you various scaling, rotating and cropping options. Play around with these to achieve your desired result then save by clicking Update on the right.
