I assumed incorrectly. I wanted to remove a "coming soon" header from the random headers. I clicked on the image radio button, and then clicked "remove image" (lose all customization). Well, the image did go away, but not the space it occupied. The remaining images will rotate correctly, but then it comes to the area where the one that was deleted was stored, and the front page shows no header at all thereby adjusting all text postings upward.
I have tried returning the image to the upload area (all sizes) but that didn't work.
I have since deleted the theme twenty eleven and then reinstalled it, but the problem returned.
Is there a file and I can edit or some way to remove that empty rotation?
Thanks for any help.
