In the Fordson theme (Moodle 3.9.1 - Fordson 3.9) the course image is also used in the course header. In an effort to make pages load faster, I use smaller course images. When this small image is used in the header it is stretched out and becomes very pixelated and hideous. Is there any way to use a common header image throughout the theme?
Or, what size image should I use for the course that wouldn't slow down page rendering when users visit?
Thank you for any help....
