I think the image max size 102400kb(100M) is hard coded in Discourse by design. The `upload_size` in app.yml is for configuring the nginx, you may want to configure the `max attachment size kb` setting which allows file size max to 1024000kb(1GB).

A 500MB image file rendered directly on the web page is horrible.
