Shell Images Appearing Automatically

[icefire]

I am new to this site I would like to have a few shells identified. I see that some people have an image link that must be clicked on in order for the image of the shell to appear, but for others, the shell image appears automatically. I currently use Photobucket image hosting and use the HTML tag for shell sales online. How do I get the image of the shell to appear automatically under my text? Also, does anyone know if this site is run from the United States? Thanks for your replies.
