How do I remove the Avatar display for all users?
There is not a setting to do this via the main interface. All you can do is make them small. At the top level of your forum go to OPTIONS > APPLICATION > CHANGE APPEARANCE, then on the black appearance toolbar select PREFERENCES > CLASSIC TOPIC PAGE > PICTURE SIZE > SMALL.
I've read some threads on this, however, under "Options" I don't have an "Editor" button to "Change Appearance" and make the Avatar smaller. Any ideas on how to make the Avatar smaller would be great too.
Unfortunately, some of the HELP pages are out of date. I suspect that you have been reading one of them.
These days, the NAML that generates the page can be edited and it would be possible to remove the the avatars. However, you should note that they include a small green ball overlay indicating when a user is online, so removing the avatar potentially removes a possibly important indicator to your users. e.g. they can see if you or another reliable poster is available to answer a question immediately.
Volunteer Helper - but recommending that users move off the platform!
