zeklein on "[Theme: Celestial - Lite] Banner Image not found"

Hi, I followed the instructions, added the advanced text widget, dragged it on the showcase front page widget, named the title and noted the code in the field: <img src="http://localhost/synthebio/wp-content/uploads/2013/06/" alt="Banniere-Synthefit3" />
Then there is no more banner on the page. When I check the code of the page, I can click on the path of the image, it opens the Index of /synthebio/wp-content/uploads/2013/06, and the image is there and shows up when clicked. So I don't understand what I did wrong.
Can someone more experienced than me could hlep me?
Thanks,
