If you have something to sell, then rent/create a host, like others do.
The Hidden Wiki is not a hosting provider.
A single image does not qualify as a website. Since the HW is a directory of websites, linking to a single image is not allowed.
Just like above: use a webserver, set up a website, like the others do.
