Hi,
If you're inserting the image at the top of the decription section on the one-page lister, that simply places the image at the top of that section on the template.
To place it above the title, you need to create a Custom Template using the Auctiva stock Chrome template and use the insert image feature on the template to place the logo above the title. Title has a placeholder tag of [TITLE] on the template.
