Hello,
Is there a function (or a script) when you open coppermine gallery that er is a popup with information? (that is editedable)

I don't think it exists though you're free to search. It might be a waste of time though since more people are using popup blockers.
take a look at http://www.dynamicdrive.com/dynamicindex8/index.html and add whatever you want to themes/yourtheme/template.html. You usually trigger pop-ups using window.onload or body.onload - see the tutorial http://www.wsabstract.com/javatutors/multiplejava.shtml
