Looker expects a public URL for your image. So make sure that wherever you store it is publicly accessible. Then, you can call it in LookML like so:
view: view_name {dimension: field_name {html: <img src=”http://www.acme.com/product_images/my_image.jpg” /> ;;}}

It's not possible to use a local image on your computer, or on the Looker server. It is also not possible to use non-public URLs, as Looker will have no way to authenticate.
