Step 6 - When the new graphic box opens click "Edit" and select "Paste"
Step 7 - Now you have the cropped pic but you still need to re-size it. Click "Image" select "Image Size"
Step 8 - When the Image Size text box opens I type "280" in the resolution box, and 1080 in the height box. As long constrain proportions is selected the rest of the boxes fill in automatically. For portrait type pics and I use 1080 in height box and 1080 in the width box for landscape type pics.
Hope this helps Al.
