You'll need to upload your image somewhere like Imgur, then right click the image once it's uploaded and select Copy Image URL (or similar).
And be glad you can't link to an image the way you're trying! It would be a humongous security hole if websites could access files on someone's computer that easily :)
My dear zystvan,
How right you are!!!
Thanks for the clue>
