Header full width possible?

Hello to the team,

thank you very much for this extraordinary great design!!!

I’vo got one problem, I hope you can help me?

Your design has a header for the different sides. Your own pictures are 19020 x 250 and use the hole wodth. That’s what I like to do with a ohn picture. But when I upload my picture, your design only allows 1500 x … – the … I can change by customize, but not the 1500 pixel.

Look, hier is my side with one of your pictures:

How can I take one of my picture into the header with full width and not only with 1500 pixel?

Best wishes from germany
