What does it mean to "Make resized images public"?

I'm using the Resize Images extension to create 120x120 thumbnails for content, keeping the original images. I was hoping to be able to just store the original full size downloadUrl on my content and do a downloadUrl.replace('.png', '_120x120.png') whenever I want to display a thumbnail. Who wants to store 2 different image urls on every piece of content?

So, I configured the extension to "Make resized images public", but the resized images still require a token and it's a different token from the original image, so I can't just get the thumbnail by adding the size params to the original downloadUrl. If I do, I get a 403 since the tokens are different.

If resized images still require a token, I'm not sure what it means to "Make resized images public". Any guidance? This seems like it would be a pretty common use case, so maybe I'm missing something.
