I'm using Organic Non Profit theme for my ngo's website. One of the theme options is to add my own header image. I can upload an image, but when it comes to the cropping screen, it only crops a limited portion of the image. Meaning the image is the wrong size. When it shows up as a header on my homepage it is too big pixelated, regardless of the dimensions of original image. How can I customize or re-size the heading so it fits properly and clearly as my header?
Also how do I make sure photos and images fit properly into theme options such as slide shows and stuff?
