watermark when showing pic

[TheOracle]

ll we want is prevent the direct access from standard users

If it's the case, then I'd strongly advise you re-evaluate your codes again as no restrictions has been set-up in order to block anonymous visits on that MOD.

so i think no secure systems are required for this last mod

It is up to you of course. Althought, I'd still recommend that you do so.

Yes there have... in the watermark.php file we check the existance of the $_SESSION['_access_is_correct']-variable... if it hasn't been set... then we don not show the pic, but an error message... i chose the page_header.php file to set our variable, because this page is included in all the gallery php-files, just to mention: details.php, postcard.php, etc etc... BUT it is not included at all in the watermark file, so if the user type the url http://mysite.com/gallery/watermark.php?id=353 wont see any image as long as the variable does not exists... Standard users won't know of course how to create this variable manually... and in page_footer.php, which is also include in all pages, we unset the variable just in case it is set yet... i think it's enough with that

It is up to you of course. Althought, I'd still recommend that you do so.

I stand by what i said before... i do not come to a reason for highly-prottecting this file...

The only thing i care in this mod is avoid users access to unmarked images...

$_SESSION['_access_is_correct']

You should really replace that

with :

Code: [Select]


$user_info['user_level'] != GUEST


instead.

i think it's enough with that

Sure. Have a good one.

I've done a general overview of the last 20 posts in this topic, and I've come to the conclussion that there's a misunderstanding with the direct-access-prevent stuff... when we say we want to prevent the direct access to the watermark php-file we are not talking about the user level... i mean guests, registered users or admins... I think you TheOracle understood all this like that.

When saying direct-access we are talking about accessing the WMark file by writting the url in the browser...

no restrictions has been set-up in order to block anonymous visits on that MOD.

I guess you mean unregistered users when you say {anonymous visits}... In fact, we dont care if the user is registered or not, logged in or not... I think that can be well configured from the 4images control panel... As i said, all we want to do is avoid direct accessing by typing the watermark.php URL in the browser...

That's why i check a  session var instead of checking the user level...

$user_info['user_level'] != GUEST

The reason to prevent this direct access is just to avoid massive downloads of pics out of the details.php page, which is bound to show the images...

P.D. Sorry 4 my bad english  ... in fact i'm a spanish speaker

My earlier posts was simply about suggested / recommended technics since you wish to use it under 4images.

[marius26]

did u try add in jpg.html template:

Code: [Select]

<img src="watermark.php?get_image={media_src}"> ? (make sure watermark.php is located in 4images root directory.)

works like a charm, no problems , check on my site, click on pic at the bottom to see this script in action.

Hi,

Is it possible to use only one of this script ability to not show full patch to image? I'm talking about watermark.php?image_id=xxx, this works great for images but how to set it to show other files? It's no needed to add watermark, just image_id=xx instead of data/media/489/game_shooting.swf in the end of site url.

Thanks.

Hi all!

First of all I want to thank the topicstarter and the people who gave help! So...Thanks! Because the main meaning of the Mod is working for me, but there is a problem:

The things I did:

- put the 'watermark.php' in the 4images root
- put a 'watermark.png' image in the 4images root
- added the line (<img src="watermark.php?get_image={media_src}">) in jpg.html

Everything is working BUT the uploaded photo is now posted 2 times, under eachother :S It looks like this -> http://www.relic-hunters.nl/gallery/details.php?image_id=3

How do I get rid of that?

Friendly regards,
Benjamin

P.S. Sorry for my bad English!

Is it ? I can't even find Instalation Notes... Don't know how to install it if the docs aren't there...

[Benjamin]

Thank you very much! Got the wrong instalation files...because the info wasn't there... Downloaded it from another place.

It's working now! Thank you!

[almighty7]

hmmm...I just got an idea about download thingie...
what if u rename in download.php

Code: [Select]

function get_file_data($file_path) {to function get_file_data2($file_path) {
and above that line add this:

Code: [Select]

function get_file_data($image)
{
  $types = array(1 => "gif", 2 => "jpeg", 3 => "png");
  if ($image_info = @getimagesize($image))
  {
    $image_create_handle = "imagecreatefrom".$types[$image_info[2]];
    if (!$im2 = @$image_create_handle($image))
    {
      die("Error opening $image!");
    }
 
    imagecopy($im2, $im, (imagesx($im2)/100)-(imagesx($im)/100), (imagesy($im2)/100)-(imagesy($im)/100), 0, 0, imagesx($im), imagesy($im));
   
    if($_GET[repeat])
    {
      $waterless = imagesx($im2) - imagesx($im);
      $rest = ceil($waterless/imagesx($im)/1);
     
      for($n=1; $n<=$rest; $n++)
      {
        imagecopy($im2, $im, ((imagesx($im2)/100)-(imagesx($im)/100))-(imagesx($im)*$n), (imagesy($im2)/100)-(imagesy($im)/100), 0, 0, imagesx($im), imagesy($im));
        imagecopy($im2, $im, ((imagesx($im2)/100)-(imagesx($im)/100))+(imagesx($im)*$n), (imagesy($im2)/100)-(imagesy($im)/100), 0, 0, imagesx($im), imagesy($im));
      }
    }
    ob_start();
    @ob_implicit_flush(0);
    imagejpeg($im2);
    $file_data = ob_get_contents();
    ob_end_clean();
    imagedestroy($im);
    imagedestroy($im2);
    return $file_data;
  }
  else
  {
    return get_file_data2($image);
  }
}

I tried to do this, but I don't find the lines in the download.php. That's because I have 4images 1.7.6.

I have a mod that makes an annotation over a watermark.php file (a transparent PNG). Unfortenately I want the Watermark to appear on the downloaded image, too, but I don't want to brand the pictures with the annotation (because I want to use the original ones for another thing).

Can anybody help me
