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?
