Defining a site in DW means setting up the site on your local computer so that all your links point to the folder in which you store all your files, css, html and jpg or gif. It also means entering all the information and passwords so that with one click you connect to your hosting server and upload all the info you have in your defined folder as and when you need to.
If you did not save your images to your folder and then did not upload them to the server, DW will not display them.
What you are telling the browser in the above statement is to look in folder "www", then folder "hk", then folder "fotooshk" and finally find the name of your image which is "lostsouls#1groot.gif". So the path to your image is wrong.
In Dreamweaver, there are 2 ways to link to your file from the Preview Panel, the one below the main file, if you do not know how to write the code yourself. After the input box where it says "Link" you can either browse to find the file by clicking on the folder icon or drag the "twirly icon" to the file in the "Files" panel. The Twirly icon is just in front of the folder icon.
Most people use a folder called "img" or "images" and put all their images into that folder which can also be divided into subfolders for different classes of image.
