Installed and activated, error in Media Settings drop-down

[presswizards]

On /wp-admin/options-media.php when trying to choose an image format for JPGs, it shows the drop-down as:

• Use original format (default)
• There has been a critical error on this website. ...

The email I received details the error:

The actual function should be strtoupper() - see here - https://www.php.net/manual/en/function.strtoupper.php

I have edited /src/Setting.php and it started working for me. I noticed it doesn't convert the images in Cover blocks, but I assume this is a WordPress limitation.

Thanks @presswizards this was fixed in #17

@wolffe is that using the original image instead of a sub-sized image?

I can't remember, actually, I stopped using it. It might have the been the original image.
