I recently tried to change the custom image header, but now I'm just getting a little x on the upper left hand corner of the header. My other blogs in wordpress.com in other themes do not to have this problem. I switched to the default and the default came up fine, but when I tried the photo again (in a variety of sizes), I still got the little x. other photos don't work either. Any ideas what I'm doing wrong?
The blog I need help with is govislandblog.com.
