Hi Stephanie,
Access the Image Editor.Within your Media Library, double-click an image. If you haven't backed up the original, click Copy, select a folder if applicable, and click Save.
Click Edit Image. The Image Editor will open. From here, an image can be adjusted in a variety of ways, including cropping, flipping, and brightening.
Enter the new dimensions. Click the resize button.
Either enter a width and height and click Apply or click and drag the box within the image and click Resize to the selected area.
Don't forget to Save.
Please let me know if you need additional assistance.
Best,
Lindsey Lawson
