Background Image size & remove gallery pics

Hello my background image is repeating, what is the exact size I need so that my background does not repeat? or is there a CSS code I need to input?

Also, I have some pictures in the gallery that I no longer want to be seen, how can I delete these pictures...I don't see a way to edit the pictures that are on the gallery page becaue they do not show on my back end.

website is http://tbministries.net/

 

Hello,

We didn't find any background image in your site.

In the gallery section it shows all images that is present in your dashboard so it is displaying all images.

Use any gallery plugin to show only selected image in gallery.

It will resolve your issue.

Thanks & Regards
