Improve error messages on Image Transform

I've been trying to work out why some images being uploaded by my users are not displaying at all (image url returns an error). Images are being displayed using the Image Transformer:



This returns the URL just fine, but doesn't acknowledge that the source image cannot be transformed. If I go to the URL in my browser, I get this error:



Took me way too long to work out why this might be the case... but in the documentation, it has the following which could probably do with being called out better.

<img width="526" alt="image" src="

While I am transforming the image to just 960x960, the uploaded source image is 7992x8006 pixels, which exceeds that stated 50MP limit. It is not clear that this limit refers to the source image or the transformed image.
