A little customization help on HTML & CSS I'm a bit rusty.

[TheGreyWizard]

So looking to do a bit of customized HTML/CSS to the basic theme for now & I'm a little rusty.   Plus I'm totally new to the hierarchy of IP software directories, so I may be searching for a while for a particular file to edit.

How would I add an image as the headers background?  

And where should I create the image folder inside of my directory?  Or is there already one I should/could be using thats part of the IP software file?

Thanks for the help.

Hello,

Are you referring to the main header (at the top of the theme), or the category headers?

If the top header, this tutorial should help!
