No Insert Image in Trial?

[David Walton]

I am trying to insert an image into a pdf document using the trial version. On this page -- Add an Image to a PDF it states...
 

To insert images:

1. On the Review tab, in the Review Tools group, click Add Image.

• If you click on the arrow next to Add Image, you can choose to add the image From File, From Clipboard or From Scanner.

2. Select the image and click Open.

3. Click the image and then resize and move it to the correct position on the page.

4. Click the elevated handle to visually rotate the image as required.

There is no Add Image option. What gives? Can or cannot an image be inserted into a pdf document by Nitro?

(I would have provided an image but this editor won't accept my image url.)
