I am trying to integrate coppermine into my website. Could some one please tell me how do I remove the top portion of the coppermine (header)?
edit themes/yourtheme/template.html with a plain text editor and remove all html you don't like. Leave the stuff in curly braces and the call for script.js intact.
In case you're trying to use a PHP include /require command to integrate coppermine into your webiste visually: you can't do that. That's not the way coppermine works. You'll have to create a theme that matches the look of your site. Please read the docs and browse/search this sub-board, it has all the information you need.
