Image link won't work

I clicked on appearance/widgets, and a a jetpack image widget to my sidebar. I’ve added a link to all of the images, but only one won’t work. When I’m logged in to the admin and go to the top to click view page, the link works, but as soon as I log out and go to the blog/reviews page to double-check, the link assigned to the bookfishbook image is no longer there. I’ve tried several times. All of the others work, except this one. I log back into admin and the link http://www.bookfishbooks.com is still entered where it says url when image is clicked, but it only works when I’m logged into admin.
