header image for Lesbar Theme

1. The blog doesn’t exist yet. So I can’t provide a link. I was hoping to resolve my problems first, obviously.
2. The code for the style.css is now at https://wordpress.pastebin.ca/181070

Please help!

From your CSS, I see this id:

#masthead {
background-image: url('images/header.jpg');
}

It’s loading header.jpg from the theme’s images directory ( wp-content/themes/Lesbar/images )

I’d make a copy of the existing header.jpg, and then replace it with your image saved to that same name. Check dimensions of the original and yours and make sure they’re similar.

I added that in from another theme called New year’s eve to see if that would insert the header image for me. Perhaps I should just post the original style.css and header.php codes so someone could tell me what to modify inorder to add a header image. THe lesbar code does not have a header image to begin with.

You asked about one theme and gave me css for another? *sigh*

Where’d you get the theme? You got a link to it on theme.wordpress.net (or somewhere else) so a more charitable helper could at least see the dang thing in action?

Ok, I published my first post at https://blog.moosewatch.com/. Since nobody knows about it yet! LOL
The header image shows up in Firefox but not in IE.
