I'm using a blank theme to customize, but I notice it uses a wp option in the design tab where the theme editor is, and it is called "custom image header" it lets you choose and upload a header image. however, I do not want to use that because my image is larger than the min size, and I just want to set the header image with my css. so I put my image in with my header div in the css, but it looks like the wp custom image header overrides my css, and it doesn't show up. I deleted the blank theme's header.jpg which was being used, but now it is just empty white space that still overrides my css background image. how can I disable the custom image header in wp? is it called with php? if so, I wasn't able to located the php that calls the image in my template files. thanks!
