I am new to wordpress and started with using the dazzling scheme. I found everything so far in the documentation / by trying out. However, I would like the header picture to be shown as in the demonstration page of the scheme (screen wide). However, when uploading the picture the “theme recommends 300 x 66 pixels”. That’s pretty small. When I crop it it even becomes smaller. How can I make it bigger, e.g. screen wide?
I found out that I can change the dimensions of the picture in header.php. I couldn’t find the source of the function “get_custom_header()” and hence don’t know where the conrete values are configured / calculated but setting it in header.php directly does the job of displaying the values in the expected dimensions.
However, irrespective of the dimensions if I add a header picture will the size be cut to a maximum width of 300 px regardless of what I choose. So if I set earlier the dimension to e.g. width = 1200px then the picture with size 300px will be displayed extremely blurred.
