View a sample here on Jane's
blog. She is a UK Stampin' Up! Demonstrator using an image in her Post Title area.  She has her small house in the front of the Post Title. Then notice there is a dotted line beneath her Post Title.

Storing Your Images
If you need a place to store your images, I would recommend and personally use
PhotoBucket (www.photobucket.com).

• Create a free account.
• Upload the images.
• Under each image you will see
  code…copy the code for DIRECT LINK and that is the path you will
  substitute and use in the code below.

Editing HTML Code
If you would like to add a graphic as a border below your post title and/or a
small image in front of your post title, you need to:

• Layout.
• Edit HTML.
• Click on Expand Widgets.
• CTRL + F to find
  "post-title" or simply scroll through your code.
• Look for the line:
  <h3 class='post-title entry-title'>
• You only have to ADD the
  HIGHLIGHTED CODE only (in the code below).
• Note the highlighted areas in
  RED (in the code below).  That is where you would replace with your image locations.
• The 1st highlighted area is for
  the small house you see in her Post Title.
• The 2nd highlighted area is the
  image with the dotted border that is sitting below the post title.
• Save Template.
• View Blog.
• You're done.
