Preventing type-in access to URL

Hello to all.
This is my issue: I created several directories with pictures in one domain.
In another domain i created links pointing to my picture´s folders.
I want to only allow access to those folders if the person comes from the links i mentioned. I don´t want type-in access to those folders.
I tried some hotlink protection with .htaccess, but they don´t protect from type-in.
Any suggestions? Thanks a lot guys.

 

my only suggestion would be to create a script that uses php to generate the image and add refferal if statements to it. And i believe u and do some crafty htaccess work to block all access except for ones with your specific refferal.

Have u tried this?

RewriteEngine on
RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} !^http://(www\.)?mydomain.com/.*$ [NC]
RewriteRule \.(gif|jpg|js|css)$ - [F]

Yes, i tried this code. But doesn´t protect type-in.

 

yea i think the best way to go is creating the php script that calls the images ... but if the refferer is not the one you want do something else.
