I need some kind of a custom rewriterule to place watermarks onto my website.
I have files called:
watermark.png
empty.png
watermark.php which includes the following code:
<?
$src = $_GET['src'];
header('Content-type: image/jpeg');
//this will prevent the watermark from showing up in the thumbnail images
$size = getimagesize($src);
if ($size[1] < 400) {
$watermark = imagecreatefrompng('empty.png');
} else {
$watermark = imagecreatefrompng('watermark.png');
}
$watermark_width = imagesx($watermark);
$watermark_height = imagesy($watermark);
$image = imagecreatetruecolor($watermark_width, $watermark_height);
if(eregi('.gif',$src)) {
$image = imagecreatefromgif($src);
}
elseif(eregi('.jpeg',$src)||eregi('.jpg',$src)) {
$image = imagecreatefromjpeg($src);
}
elseif(eregi('.png',$src)) {
$image = imagecreatefrompng($src);
}
else {
exit("Your image is not a gif, jpeg or png image. Sorry.");
}
$dest_x = ($size[0] - $watermark_width) / 2;
$dest_y = ($size[1] - $watermark_height) / 2;
imagecolortransparent($watermark,imagecolorat($watermark,0,0));
imagecopyresampled($image, $watermark, $dest_x, $dest_y, 0, 0, $watermark_width, $watermark_height, $watermark_width, $watermark_height);
imagejpeg($image, "", 95);
imagedestroy($image);
imagedestroy($watermark);
?>
All of these files are in the root directory.
I just need the htaccess rewriterule code if anyone can shed some light as to what it would be.
I’ve found the same system being used on a wordpress site with the following rewrite - RewriteRule ^(.)wp-content/uploads/(.) $1watermark.php?src=wp-content/uploads/$2
Sadly i don’t know where to put this in my htaccess file and what to edit the file paths too?
I’m using vBulletin with VbSEO so my images are at /attachments/ even though they are in root/images/attachments
Really need this sorted tonight as i’ve got some important images going up tonight that i don’t want stolen.
Many thanks,
Andy
Ok i found a different plugin which i think could be altered.
All i need is so that it only watermarks on images that are 400px wide or greater.
Here is the vBulletin code:
// begin variables
// the path to the PNG file that you want to overlay with
// must be on the local machine, not an http:// URL
$WATERMARK_PNG_FILE = '/home/aruffell/public_html/watermark.png';
// how you want to position the watermark enter either center or bottom_left
$WATERMARK_POSITION = 'center';
// user you want to see watermarking on - this is just for testing
// set to 0 to work for all users
$VB_USER_ID = 0;
// end variables - you shouldn't need to edit below here
// if there's no filepath to work with there's nothing we can do
// we also need the watermark file to exist
// if $VB_USER_ID is specified (for testing) show it just them
if(! empty($attachpath) && file_exists($WATERMARK_PNG_FILE) && ( $VB_USER_ID == 0 || $GLOBALS['vbulletin']->userinfo['userid'] == $VB_USER_ID )) {
// derive output name
$fo = preg_replace('/\\.attach$/', '.marked', $attachpath);
// image doesn't exist or thumbnail is newer than the cached file - create a watermarked version
if( (! file_exists($fo) || filemtime($WATERMARK_PNG_FILE) > filemtime($fo) || true) && $fo != $attachpath ) {
// decide what image type it is
if( preg_match('/\\.png$/i', $attachmentinfo['filename']) ) {
$im = @imagecreatefrompng($attachpath);
} elseif( preg_match('/\\.jpg$/i', $attachmentinfo['filename']) ) {
$im = @imagecreatefromjpeg($attachpath);
// create an empty truecolor container
$tempimage = @imagecreatetruecolor(@imagesx($im), @imagesy($im));
// copy the 8-bit gif into the truecolor image
@imagecopy($tempimage, $im,
0, 0, 0, 0,
@imagesx($im), @imagesy($im)
);
// copy the source_id int
$im = $tempimage;
}
// open the watermark image
$wm = @imagecreatefrompng($WATERMARK_PNG_FILE);
@imagealphablending($wm, false);
@imagesavealpha($wm, true);
// catch opening problems
if($im && $wm) {
if($WATERMARK_POSITION == 'center') {
$pos_x = (imagesx($im) / 2) - (imagesx($wm) / 2);
$pos_y = (imagesy($im) / 2) - (imagesy($wm) / 2);
} else {
$pos_x = imagesx($im) - imagesx($wm) - 10;
$pos_y = imagesy($im) - imagesy($wm) - 10;
}
// merge the files together
$copy_worked = @imagecopy($im,$wm,
$pos_x, $pos_y,
0, 0, imagesx($wm), imagesy($wm)
);
}
// write out the new image
if($copy_worked) {
// decide what image type it is
if( preg_match('/\\.png$/i', $attachmentinfo['filename']) ) {
@imagepng($im,$fo);
} elseif( preg_match('/\\.jpg$/i', $attachmentinfo['filename']) ) {
@imagejpeg($im,$fo);
} elseif( preg_match('/\\.gif$/i', $attachmentinfo['filename']) ) {
@imagegif($im,$fo);
}
}
}
// check that the new file is there - if so open the file pointer to it
if( @filesize($fo) > 0 && $fp2 = fopen($fo,'rb') ) {
// re-send image size header
header('Content-Length: '. filesize($fo));
@fclose($fp);
$fp = $fp2;
}
}
Any ideas?
Thanks,
Andy
