General Support: Move photos outside of web access...

platipuss,

Try this. Create a new .htaccess file in your thumbs/ folder with the following code in it:
<IfModule mod_rewrite.c>
RewriteEngine on
RewriteCond %{HTTP_REFERER} !^http://www.yourdomain.com/path_to_plogger_install_gallery_if_not_in_root/.*$ [NC]
RewriteCond %{REQUEST_FILENAME} .*jpg$|.*bmp$|.*jpeg$|.*gif$|.*png$ [NC]
RewriteRule \.(jpg|bmp|jpeg|png)$ - [N,F,L]
</IfModule>
Just change the "http://www.yourdomain.com/path_to_plogger_install_gallery_if_not_in_root/" to whatever you have set up on your server.
That should only allow someone who is looking at your images through your protected Plogger gallery or if they come directly from that page as well.

Please be advised that this will stop almost everyone, but it *is* possible to spoof your HTTP_REFERRER to make the server think the images are being accessed from your Plogger install.

If you want to protect the original images, do the same for the images/ folder or uncheck the "Allow Full Picture Access:" in Admin -> Options (although the latter will not allow direct or indirect linking to the images, so it won't even allow your Plogger install to link to them).

you can add "deny from all", but then your thumbnails will probably not show up when viewed from your protected gallery either. :-)
The code I posted above should allow your protected gallery to access the thumbnails, but nothing else.
