How do I add a background image to my header in the Symmetry theme?

Store Design

Hello. I am trying to add a background picture to my header in the Symmetry theme. I have tried several solutions suggested in other posts for other themes but have not been successful. Any help would be greatly appreciated. I am a novice in HTML, CSS and Liquid. Thank you. (and my wife will say thanks as well!)

Hi @tnzigs , can you share your store url and the image you want to put as a background?

Thanks for the response. Our store URL is sweetmaggierose.com. It is temporarily password protected with temp12. The link to my image is https://cdn.shopify.com/s/files/1/0831/3929/7586/files/Header_Wallpaper_a71c87a1-fbcf-423f-8013-dbd62104737f.jpg?v=1703987982

Again, thank you for the help.
