Steps to reproduce

1. Clone the AWX repo.
2. Navigate to the source files for the User Guide in GitHub at: https://github.com/ansible/awx/tree/devel/docs/docsite/rst/userguide (locally they should reside in /Users/you/awx/docs/docsite/rst/userguide).
3. Open an .rst file, as applicable, to edit it. Search all image directives and place the :alt: code block beneath it. See syntax in Expected Results below.
4. Commit the changes, open a PR.

Expected results

The following codeblock added to each image with its specific descriptors filled in:

.. image:: ../common/images/image-filename.png
   :alt: Phrase that describes image

or

|Resource - alt text describing image|

.. |Resource - alt text describing image| image:: ../common/images/image-filename.png
   :alt: Phrase that describes image

Actual results

Some images don't have the alt text info in them.

Additional information

Example from Credentials section of the User Guide:

To add permissions to a Team:

1. Click the **Add** button, which opens the Add Permissions Wizard.
