Does anyone know if you can delete the header and just have your customized header on the Cutline design in WordPress? How to delete?

If you uploaded an image that doesn’t match the exact dimensions of your current theme’s header, you will need to crop it. Just select the portion of the image that you’d like to use for the header, then click Crop and Publish. Once you see the Header Updated message below, you can visit your site to see how it looks.

The image should appear immediately. If it does not, please contact Support. Be sure to provide a detailed description of the header image that you attempted to upload and/or attach the image file so that we can take a closer look.

Many of the themes have other customization options. If you wish to remove the blog title (and tagline, if it appears) from the header, you can select uncheck the Show header text with your image option. If you wish to show the blog title and tagline, you also have the option to change the text color using the Text Color option.

Media -> Library and clicking on “Delete Permanently” underneath the image. To add a header image without cropping, first you must use a theme with Flexible Header support (check the list below). Once you’re sure you are using a theme that has flexible header support, go to Appearance?

Header? Upload an image and click the “Skip Cropping, Publish Image as Is” button. The header image will be added without any cropping so you can use one that is taller or shorter than the size defined by the theme when you crop.

Not all themes have support for flexible headers yet, but we are working to add support for as many themes as possible over time. You can see current list of themes that support flexible headers by looking at the table below or the flexible header filter in the Theme Showcase. Here is the official, current listing of all themes that support custom header images, image dimensions, and the download link to the original header image (if there is one).
