How To Free Rotate an Image
Assuming you already have an image on your page, move the cursor over it and select it so that there will be 8 Green Squares around it.
Go to the Drawing Toolbar on the bottom of the page and select the down arrow on the right side of the Effects Icon, which will open a popup menu.
Select the 1st Icon for Rotation.
The 8 Green Squares around the Image will change to 8 Red Circles.
4 Arrows in each corner will be for Free Rotating the Image.
To Free Rotate, move the cursor over 1 of the corner Arrows.
The cursor will change to a Rotation Handle.
Hold down your mouse button and move in a Clockwise or Counterclockwise direction.
Then you will have a Rotated Object or Image as the case may be.
