No error message when invalid image uploaded

[puritas]

With the following set up:

Input Field Type: File
Only Accept Image Files: Yes
Max file size: 300000
Min dimensions: 1440x700
Max Dimensions: 1700x1200

If a user attempts to submit a file that's larger than max file seize or smaller than min width there's no error message.

Any idea where to start debugging or on a custom modify error to use?
