changing sidebar titles to images

I am using the cutline three coloumn split theme. I want to change the titles of the sidebars (archives, search, recent posts, blogroll, etc.) to images (jpg files with font from my computer to match the font in the heading). I have an example of what I want this to look like on the left side in a text box widget with html <img src=”….”> but I can not figure out how to do this on the other widgets? I know this is possible, I’ve seen it on other wordpress blogs, I have searched and have seen lots of questions on how to do this, but no answers?
