Thanks for the response. I do have other plugins installed but they are inactive. I know Smush integrates with Hummingbird so I will check the Smush settings so that our theme isn’t overdoing it.
Here’s an example of exactly what’s happening.
I uploaded an image on 8/2. On that original image, 17 different sizes were created.
If that were it, I think that would be okay. But, even though I haven’t uploaded that image again, something creates a new copy of it and another 17 sizes are created as well. That happened on 8/4.
This is what I’m very interested in preventing.
