Another watermark mod (simpliest available) GD2 compatiable

[surjo_becarz]

I have done every thing as instructed but it's not working it'a giving out this error Warning: imagecreatefromjpeg(albums/userpics/10018/thumb_04112005%28019%29.jpg): failed to open stream: No such file or directory in /home/bdcarzc/public_html/gallery/include/watermark.class.php on line 176
Could not create from JPEG

  It worked for me!  see it in action on cpg 1.3.3 : http://gallery.tefilah.net

Difficulties: 

• unusual file names always crash gallery: I downloaded a wonderful free ap to strip symbols and spaces from windows filenames: called ReNamer http://www.snapfiles.com/freeware/system/fwfilerename.html ; everything works when new files are uploaded
  
• xpPublisher mod doesn't work: user1 field receives value "undefined" rather than "YES" : this is in referece to this post : http://forum.coppermine-gallery.net/index.php?topic=8885.msg40525#msg40525
  
• I didn't want to force each photo to show the watermark, so I just turned it on for ALL like this: I took joeyphoto's advice: http://forum.coppermine-gallery.net/index.php?topic=8885.msg107683#msg107683 make sure to comment out that very last bottom "}"
• did not understand instructions for defining internal/external paths; I ended up using the modified watermark.class.php posted here: http://forum.coppermine-gallery.net/index.php?topic=8885.msg79092#msg79092 which also gives you the option to place the watermark in the center of the image and reduces the minimum size ratio needed to display the watermark on intermediate images

This is very nice 

I'm using ver 1.42 and I had to try it for myself, so from a first look it works perfectly with a small change to the code.

The only problem with this script is that the watermarked files aren't getting deleted so it can overload the hard-disk if you don't delete them manually.

In order to install on 1.42, do the following:
1. Copy the file watermark.class.php into the include directory (all files are attached in the first message)
2. Copy the file watermark.png to the image directory
3. Create a directory under the albums directory and call it "watermark". CHMOD it to 777.
4. Now here is the change - instead of changing the file functions.inc.php as instructed, replace the following lines:

In the file include/functions.inc.php

Look for this line:

Code Select Expand

$filepathname = $url_prefix[$pic_row['url_prefix']]. path2url($pic_row['filepath']. $pic_prefix[$mode]. $pic_row['filename']);

Replace with these lines:

Code Select Expand

    if ($pic_row['user1']!="YES")
    {

$filepathname =  $url_prefix[$pic_row['url_prefix']]. path2url($pic_row['filepath']. $pic_prefix[$mode]. $pic_row['filename']);

    } else {
require_once "include/watermark.class.php";
//$watermark_file_location = 'images/watermark.png';
$watermark_file_location = 'images/watermark.png';
$picture_location = $url_prefix[$pic_row['url_prefix']]. path2url($pic_row['filepath']. $pic_prefix[$mode]. $pic_row['filename']);;

$img = new Watermark();
$img->watermark_file = $watermark_file_location;
    $img->add_watermark($picture_location);
$filepathname = $img->image_tag;

    }


Remember that you must put the value "YES" in the field user1 in order for it to work.

I wanted it to automatically watermark all the images so I removed this condition like this:

Code Select Expand

   
    if (1!=1)
    //if ($pic_row['user1']!="YES")
    {

$filepathname =  $url_prefix[$pic_row['url_prefix']]. path2url($pic_row['filepath']. $pic_prefix[$mode]. $pic_row['filename']);

    } else {
require_once "include/watermark.class.php";
//$watermark_file_location = 'images/watermark.png';
$watermark_file_location = 'images/watermark.png';
$picture_location = $url_prefix[$pic_row['url_prefix']]. path2url($pic_row['filepath']. $pic_prefix[$mode]. $pic_row['filename']);;

$img = new Watermark();
$img->watermark_file = $watermark_file_location;
    $img->add_watermark($picture_location);
$filepathname = $img->image_tag;

    }

This way, the first line will be ignored always, and you can still go back to the original code if you wish.

Have fun and thanks for the mod,
