I have a photo of 2 Mb on disk and 4032x3024 (iPhone 8 size) and I’m not able to post this photo on my discourse because of this error:
Sorry, that file is too big (maximum size is 102400kb). Why not upload your large file to a cloud sharing service, then share the link?
How you can see, I increase the size to maximum size allowed. Even the max image megapixel is to 150.
Why it this happens?
