The link you put up looks like there is no photo on the site to display.
To upload a photo to a web site, the site must have a form on the webpage to initiate the upload. They usually have a text box where you can type in the path on your computer to the photo and a button labeled "Browse." First click on Browse, navigate to the photo. That could be what "link image" means on that site. Once you have selected the photo, click on "upload." and the photo should go to the site.
If you click on "settings" at the top right of this page and select "Picture" you will see an example of how it works. The terminology they're using may be different but the procedure is you first have to find the path to the photo on your computer then initiate the transfer.
