Pretty new to wordpress.com and the forums, not new to CSS. I apologize if this is an FAQ but I couldn't find forum search.
I'm using Chris Pearson's Cutline theme, but I want to use a header taller than the original height of 140px (mine is 770w x 328h). I can upload my image and am then taken to the cropping page where it displays my new header, however I'm unable to extend the cropping tool past the original 140px height.
How do I prevent the cropping page from limiting my header height?
