Question mark / strange file on homepage

Hello, There is a question mark box underneath the main image on my welcome page datingstories.me Can you please help me get rid of it? This is what the Wordpress forum had to say about it: Hi, it seems to be remote content (just like the first(main) image is) but the remote host had removed this image (can you check in backend to see what files are attached to the post?) As far as I can see, only the image is attached to this post. Thanks for your help
