Its very Simple, All You have to do is Upload the Wallpaper Preview at Imageshack.com or tinypic.com as Galmed said, to get a URL Adress for the Image.
Then, the Same Way as You Post Your message Here. Hit the Add Reply Button and then click on the 2nd Box from the Right of the Smiley Box.
You will be asked to enter a URL. There, You have to copy the URL that You got for the Image You Uploaded and Paste it here in this Box. Thats How You would get a Preview.
Hope You got it. If Not, You can Always feel Free and ask for Help Again.
