You’re right. Any indication I got from meta is that `max image size kb` is the maximum allowed uploaded image size. Over this size and the image upload will simply be rejected.

It has been said that Discourse will scale down _very large_ images in the background; how large is very large, and how much to scale down has always remained a mystery.

Now, @zogstrip, does it mean that `max image size kb` is actually the trigger level for the scale down itself? In other words, if I have:

- Max upload size in `app.yaml` = 20MB
- `max image size kb` = 1MB

My original understanding is that uploading any image above 1MB will be rejected.

Now @zogstrip is saying that as long as the image is no larger than 20MB it can still be uploaded. But then in the background it will be scaled down (because \>1MB), half-dimensioned three times, essentially making it 1/64 of the size?
