I would like to avoid the direct access to images in a directory. Please let me explain what i need exactly becouse its a little complicated ;)

I have a directory called "member", and in this directory are the member directorys like "thorsten" and in this directory are the images of the members. So my it looks like this:

```
    index.php // The index.php is in the same directory as the member directory ;)

    member/thorsten/Thorsten-fTeVtE-Preview-01.jpg
    member/thorsten/Thorsten-gZ4Cd3-01.jpg

    .htaccess // The .htaccess should be here too :)

```

As you can see the member thorsten has two images now, one has the Word "Preview" in it and one not. The thing that i need is that i would like to disallow the direct access through an url to the image to all images that has NOT the word "Preview" in the file name.

And another tricky part is that the user directorys like "thorsten" in this example can have any name, for instance there can be also:

```
    member/melanie/Melanie-fh3wxcg-Preview-01.jpg

    or

    member/conny/Conny-fh3wxcg-Preview-01.jpg

```

I hope you understand what exactly i mean, the member directory name should be variable ;)

Thanks :)
