This script adds a text watermark to an image. No matter what number I put into this script under $fontsize = ? for changing the font size, it does not change when viewing the image. I've tried adding px and em to the number to see if that would help, but it made the images not show up altogether. Can anyone please help me? Here is the code: <?php function watermark_text($src_image,$watermarkstring,$watermark_location,$watermark_margin=0) { $file = $src_image; $size = getimagesize($file); $w = $size[0]; $h = $size[1]; $fontsize = 30; if(stristr($file,".jpg") || stristr($file,".jpeg")) { $image=@imagecreatefromjpeg($file); } else if(stristr($file,".png")) { $image = @imagecreatefrompng($file); } else { exit("Sorry, only *.jpg/*jpeg and *.png images are supported"); } $color = imagecolorallocate($image, 200, 200, 200); $xi = 0; $yi = 0; $strlen_watermark = strlen($watermarkstring); switch($watermark_location) { case "topleft": $x = $watermark_margin; $y = $watermark_margin; break; case "topright": $x = $size[0] - $fontsize * strlen($watermarkstring); $y = $watermark_margin; break; case "center": $x = $size[0]/2 - $fontsize * strlen($watermarkstring)/2; $y = $size[1]/2 - $fontsize ; break; case "bottomleft": $x = $watermark_margin; $y = $size[1] - $fontsize - $watermark_margin; break; case "bottomright": $x = $size[0] - $fontsize * strlen($watermarkstring); $y = $size[1] - $fontsize - $watermark_margin; break; default: $x = 0; $y = 0; break; } imagestring($image, $fontsize, $x, $y, "$watermarkstring", $color); if(stristr($file,".jpg") || stristr($file,".jpeg")) { header("Content-type: image/jpeg"); imagejpeg($image,NULL,100); } else if(stristr($file,".png")) { header("Content-type: image/png"); imagepng($image); } else { exit("Sorry, only *.jpg/*jpeg and *.png images supported"); } ImageDestroy($image); }//function ////////////////////////////////////////////////////////////////////////////////// function watermark_image($image_path_src,$image_path_watermark,$watermark_location,$watermark_margin=0) { if(stristr($image_path_src,".jpg") || stristr($image_path_src,".jpeg")) { $image=@imagecreatefromjpeg($image_path_src); } else if(stristr($image_path_src,".png")) { $image = @imagecreatefrompng($image_path_src); } else { exit("Sorry, only *.jpg/*jpeg and *.png images are supported"); } $size = getimagesize($image_path_src); $w = $size[0]; $h = $size[1]; $src_x = 0; $src_y = 0; if(preg_match("#\.png$#i",$image_path_watermark)) $watermark_image = imagecreatefrompng($image_path_watermark); else if(preg_match("#\.gif$#i",$image_path_watermark)) $watermark_image = imagecreatefromgif($image_path_watermark); else if(preg_match("#\.jpe*g$#i",$image_path_watermark)) $watermark_image = imagecreatefromjpeg($image_path_watermark); else exit("Sorry, only *.gif, *.jpg and *.png watermarks are supported"); $size_watermark = getimagesize($image_path_watermark); $dst_w = $src_w = $size_watermark[0]; $dst_h = $src_h = $size_watermark[1]; switch($watermark_location) { case "topleft": $x = $watermark_margin; $y = $watermark_margin; break; case "topright": $x = $size[0] - $size_watermark[0] - $config["watermark_margin"]; $y = $watermark_margin; break; case "center": $x = $size[0]/2 - $size_watermark[0]/2; $y = $size[1]/2 - $size_watermark[1]/2; break; case "bottomleft": $x = $watermark_margin; $y = $size[1] - $size_watermark[1] - $watermark_margin; break; case "bottomright": $x = $size[0] - $size_watermark[0] - $watermark_margin; $y = $size[1] - $size_watermark[1] - $watermark_margin; break; default: $x = 0; $y = 0; break; } $dst_x = $x; $dst_y = $y; imagecopymerge($image,$watermark_image,$dst_x,$dst_y,$src_x,$src_y,$src_w,$src_h,25); if(stristr($image_path_src,".jpg") || stristr($image_path_src,".jpeg")) { header("Content-type: image/jpeg"); imagejpeg($image,NULL,100); } else if(stristr($image_path_src,".png")) { header("Content-type: image/png"); imagepng($image); } else { exit("Sorry, only *.jpg/*jpeg and *.png images supported"); } ImageDestroy($image); } ///////////////////////////////////////////// include(dirname(__FILE__)."/../common.ini.php"); $item = $catalog->items->get("WHERE id=".(int)$_GET["id"]); switch($config["watermark_type"]) { case "text":watermark_text("../rwx/".$item["file"],$config["watermark_text"],$config["watermark_location"],$config["watermark_margin"]);break; case "image":watermark_image("../rwx/".$item["file"],"../rwx/".$config["watermark_image"],$config["watermark_location"],$config["watermark_margin"]);break; } ?>
