Background Images

Hi there,

I am taking over my companies website, which I did not create. I am in the process of making it more user friendly, but am having great difficulty with the background images. Some of them do not fit well on the mobile version and I am trying to change this. I have tried to look through multiple videos and read forums but I cannot seem to get it to work. If you have any suggestions on how I could fix this, that would be great!

Thank you
