Do noindex tags on subdomain pages affect image indexing?

Maybe stupid question, but I have to ask:

I’m hosting my images on a subdomain. My main site is and images are stored on

Subdomain is just a simple html page – when you type its address in the browser, a blank page with “access forbidden” will pop up. If I put a noindex tag in that page (index.php), will my images stop indexing as well? The html page is called index.php and you can find it in the /media folder (images are stored here as well).

Of course I want to keep indexing my images.
