I recently migrated my site from localhost to a host server. The custom header image on my site is missing as well as the custom background. The images themselves reside in the media library and are visible. When I attempt to re-establish my custom header from the Appearance ->Header panel, the panel doesn't detect the image. It will load each default header image without a problem but it doesn't see the images I have in my Media Library. Oddly, the images I have included in my widget areas and page content work fine. I'm using the Weaver II theme.
