I would assume you could look in your local profile to validate if anything is in fact being cached.

To do so you would go to: C:\Users\YourUserProfile\AppData\Local\Mozilla\Firefox\Profiles

Once there open the profile and review the cache directories.

So I found a better solution for you I think.  In the location bar within Firefox type about:cache and hit enter.

*The location bar is where you type in web URLs.

about:cache
about:cacheso are images being cached?

hard to tell because there could have been old images before I did about:config and turned off cache

So yours shows 0 entries where as mine shows what it looks like when caching is enabled.  See mine below:

You can also look in your "Thumbnails" directory to see if there are any images being cached in your  C:\Users\YourUserProfile\AppData\Local\Mozilla\Firefox\78oowcux.default\Thumbnails directory

yes thumbnails are cached on my computer
so when I turned off cache it was from the beginning of time (deleting existing windows explorer folder) and not as of september 2014?

I just did a test and that setting does not prevent the thumbnail caching so take a look at the below steps to get rid of image caching (I tested it and it worked):

1.Open Firefox. Go to the address bar, type about:config and hit [Enter].
2. It might warn you not to play around. Click “I’ll be careful, I promise!”
3. Type “prefetch” into the search box. You should see an option called “network.prefetch-next” which you can double-click to change to “false.”
4. Search for “cache.disk” this time. Change “browser.cache.disk.enable” to “false” and change “browser.cache.disk.capacity” to “0.”
5. Close and re-open Firefox.
6. Hit [Ctrl] + [Shift] + [Delete] to bring up the “Clear Recent History” box. Change your time range to “Everything” and make sure “Cache” is checked. This erases the entire disk cache.
7. For the really paranoid, install CCleaner (don’t install anything else it offers to install while you do it), find the “Wipe Free Space” option at the bottom of the left column, right-click on it, and choose “clean.” (It might warn you that it’s going to delete stuff, but proceed anyway.) This erases the contents of all of the empty space on the hard drive, including anything that was in the disk cache you just deleted and anything that has ever been deleted from the computer.
8. [Update for newer Firefox versions] Firefox stores thumbnails of pages you visit for the new “New Tab” page previews. To get rid of this while you’re in about:config, right-click somewhere and go to New -> Boolean, call it browser.pagethumbnails.capturing_disabled and set it to true. Restart Firefox and no more behind-your-back thumbnails.

Open in new window

Update: These settings are in addition to your original config change.

Best example is a screenshot of your cache so I could compare.
Thanks.
