You have an image in a "custom block" placed in the left column of the Top Page, yes?
If so then go to Admin>Blocks Admin and find your block in the listings. Then click on the "Edit" link in the right-hand column.
Use the "Visible in" select-box to choose the page(s) where your blcok will show. You can make multiple selections by holding down the "Ctrl" key on your keyboard in the usual way.
