But the user mentioned "blur," so maybe they want the link itself to be disguised in some way. Could be using placeholders or fake domains that resolve to internal IPs or something else. However, that might not be feasible for public access. Another thought: using image URLs that point to a script which serves the actual download. For example, a link like www.example.com/image.jpg could actually be a script that serves pspiso.dwl.iso, but that requires proper MIME types and configurations.
