thanks for your answers. My thoughts:
1. I’m no coder, i’m a graphic designer … so if i understand that right that php goes in the theme options? and i change that vimeo to whatever i need? and if i have 2 or 3 i duplicate the »if …« part …?
2. That’s a bad choice to make that the standard. I’ve set up my own privacy site anyway and won’t use that wp feature at all (no need, no sense). This means i have to leave it as is > or put it as html in the copy of the php part?
3. Videos load direcly, but Google Map loads blank > shows up again after reload.
Allowed to show an idea? Just make a input field for the copy in theme options at privacy > done?
