Re: Storing Images #2

If its outside the html root you would need to create a symlink pointing to the appropriate folder

%> ln -s /path/to/hidden /path/to/public *however this is very insecure

Then if your wise you could create a simple image serving script to prevent direct navigation by checking the referring page request vs. an array of allowed script names, the folder and filename being requested etc. Kind of like an intermediary to ensure your (*assumed world readable and writable) images directory is somewhat unusable except by your scripts.

If you did it in this manner you could simply call the image as you would regularly.. <img src=image/image.jpg>

Of course this is all theoretical as I have never done this before but if you also block your upload script (*an assumption based on the question) you could limit it using apache hosts_allow and hosts_deny directives.

Or you could use your upload script to copy the files to the server, then once the application publishes the site you could use it to copy the image files from the writable directory (above the web root) into the public images directory.

The best method would require the following:
1. a sub domain with limited access using apaches hosts_allow and hosts_deny directives
2. a world read/writable folder located outside of the web root
3. script prevention by checking referring scripts as well as perhaps an internal allowed ip range directive 4. a command line, crontab entry to move image files from the world read/writable folder into the public/images folder

You should look into linux folder and file permissions vs. the user and group that is running as your web server. Just a few suggestions. Keep in mind that the only real way to keep your stuff secure is to cut the cord.

If you put the images OUTSIDE of the webroot/docroot/public_html
folder (whatever you have), then a user cannot directly navigate to
the file.

e.g.
         /home/sites/your_site/public_html/images/image1.jpg

         http://www.yoursite.com/images/image1.jpg would probably work.

But ...

/home/sites/your_site/public_html/getImage.php
/home/sites/your_site/hidden_images/image1.jpg

Now, there is no way I can load image1.jpg from my browser. I have to
use getImage.php, which I assume would require me to login or
authenticate myself in some way.
----------------------------------------------------------
I have my photos in /public_html/img/gid directory and with this path:
<img src='http://www.mydomain.com/img/{$gid}/{$photoFileName}' in getImage.php the server displays the photos.

Now if I put my photos outside of the public_html like this:
/hidden_images/img/gid

what would be the correct path to the photos in the getImage.php script?
