No need to leave the document itself and use a 3rd party software to edit images and pictures. Now, you can change images right inside the document itself.
Select the image/picture within the document and:
Use the toolbar
Format Menu
Right-click the image and use the drop down menu
You can:
crop
rotate
re-color
adjust brightness
change contrast
add transparency
add borders
change to a different image
This feature can be very helpful and save time.
Use The Drop Down Menu
Editing Images - Image Options
Use the "Image Option" feature to change colors of images, adjust transparency, brightness, and contrast.
You can also choose negative colors. A nice feature is that the image is changed, not the background.
Revert Back To Original Image
You can always revert back to your original image. Choose, "No Re-Color" in the Image Option sidebar.
