[iannnnn]

(sorry for my quite bad english)


hi all,
i'm using 4images for 9 months in my website 
it's really the best fantastic application that i've ever seen!

okay, let's see my problem.

my website has many pictures that i allow everybody to see and download them
but i don't like someone who grab the direct-links to the download buttons
example :

Code: [Select]

www.myweb.com/gallery/download.php?action=zip&image_id=xxx
it's made me really confuse about the hits number of each images that less than the download number
when i check at my web statistics, they told me -- "hey, your image gallery was stolen by someone  "


so...
i would like to use the mod that help me to restrict everyone to view my picture's detail before download it
maybe i have to modify some lines in the /include/download.php, or not?

pleasssseeeee --- i wanna recieve some helps form the heroes here 
thanks for 100 times !!

1) in includes/sessions.php find:

Code: [Select]

$user_info = $site_sess->return_user_info(); insert below:

Code: [Select]

if (!isset($allowdownload) || empty($allowdownload))
{
  $site_sess->set_session_var("allowdownload", "");
}
2) in includes/functions.php find:

Code: [Select]

    $allow_download = 1;Insert below:

Code: [Select]

    $site_sess->set_session_var("allowdownload", time());
3) in download.php find:

Code: [Select]

$main_template = 0;Insert below:

Code: [Select]

$allowdownload = 1;Then find:

Code: [Select]

  if (!check_permission("auth_download", $image_row['cat_id']) || !$image_row) {
    header("Location: ".$site_sess->url($url, "&"));
    exit;
  }Replace it with:

Code: [Select]

  if (!$image_row || !check_permission("auth_viewcat", $image_row['cat_id']) || !check_permission("auth_viewimage", $image_row['cat_id'])) {
    header("Location: ".$site_sess->url($url, "&"));
    exit;
  }
  else
  {
    $allowdownload = $site_sess->get_session_var("allowdownload");
//    if (!check_permission("auth_download", $image_row['cat_id']) || (time() - $site_sess->get_session_var("allowdownload") > 60*5))
    if (!check_permission("auth_download", $image_row['cat_id']) || !$site_sess->get_session_var("allowdownload"))
    {
      header("Location: ".$site_sess->url(ROOT_PATH."details.php?image_id=".$image_id, "&"));
      exit;
    }
  }(note, this step also fixes a bug in 4images which allow people download images that they were not allowed to view!)

In step 3 I've added 5 minutes timeout, meaning visitor must click on download button in within 5 minutes after opening details page, otherwise it will simply refresh the page with another 5 minutes timeout. To enable this feature, use the commented out condition line.
P.S. all this not tested

Cool Idea... (o:

THANKS!!!
now i can fix my bugs and say yahoooooowwwwwwuuu 

for someone who want to know about an effect of this mod :
when users use direct-links to download pages, they will grab a 'download.php' instead. 

i tested it in:
- 1.7
- flashget
- mozilla firefox 1.0.7
and it works!

thanks a lot again!

You got me confused on that one...what do you mean?
It should simply redirect to details page of the image instead and if you try to right click on the link and do save as, it should save html page of the details page...

Oh sorry.
i typed mismatch
