image link fix in funny_image

Hi, I found out what Markdown was. I changed the original README file with a new link to an image. I tried to open the README.md file in a browser to check the link but that didn't work. I commited it and hoped for the best, but the image didn't display in the github browser page. I found a site called http://dillinger.io/  where i could test the Markdown in advance. Is this the best way to test?  
Thanks
