Breadcrumb Backgrounds and page headers

Hi!

1. I’d like to know if there’s a way to customize a separate breadcrumb background image for each page?
2. How could I lose the text in each page header noting where the page is located, like Home»About?
3. Is there a way to lose the name of the page from each page header all together? If I’d like to add a small icon instead, for instance. Could I the add it instead of the text or should I insert it to the header image?

Thank you in advance!
