How to hide links of images?Applying restrictions to the uploaded folder?

Hi All,

Friends can you tell me how to make images such that noone can click on it everyone can just view it inside the post but when takes the mouse pointer on it,its not possible to click on the image to open it separately in browser with the image link to our uploaded directory example

we can see the image but its not possible to click on it however if we do a right click and copy image location its there

https://fastcache.gawkerassets.com/assets/images/17/2011/04/1030-flyer_s-rights.jpg

which is ok but on removing the file name at the end

https://fastcache.gawkerassets.com/assets/images/17/2011/04/

It gives error

Forbidden

You don’t have permission to access /assets/images/17/2011/04/ on this server.

while on my site it shows the complete folder even on removing the file name how to restrict that
