I’ve often added in an image to Google Docs, only to realize that it needed to be cropped. It’s been a source of annoyance to me that I had to crop the image in another program and re-import it to Google Docs. This problem no longer exists!
To crop an image that you’ve inserted in a Google document, select the image and select Crop from the Format menu.
I think that this is a great enhancement to Google Docs. How much will you use this new feature?
