[execute]

header("Content-Type: image/jpg") or image/jpeg should work fine

how are you calling the images/script?

Hi guys, thanks for the replies. The code I am using is

$flag1result = mysql_query("SELECT flag FROM cf_flag, propertyFlag WHERE propertyID=".$row['propertyID']." AND propertyFlag.flagID=cf_flag.flagID") or die(mysql_error());
							  while ($flag1row=mysql_fetch_array($flag1result)) {
							  	if ($flag1row['flag']=="Sold STC") {
									$flagtype = "soldstc";
								}
									if ($flag1row['flag']=="Under Offer") {
									$flagtype = "underoffer";
								}
							  }




						  $query=("SELECT domainURL,imageName from image where propertyID=".$row["propertyID"]." order by imageName limit 1");
							  $result2=mysql_query($query);
							  //$image=mysql_num_rows($result2);
							 //add watermark 


							 if ($flagtype=="soldstc") {
						  		 $watermark = imagecreatefrompng('images/watermark_soldstc.png');
							 }
							 if ($flagtype=="underoffer") {
						  		 $watermark = imagecreatefrompng('images/watermark_underoffer.png');
							 }
							 if ($flagtype=="") {
							 	 $watermark = imagecreatefrompng('images/watermark_blank.png');
							 }
							 $watermark_width = imagesx($watermark);  
							 $watermark_height = imagesy($watermark);
							 //

							   IF ($row2 = mysql_fetch_array($result2))
							   {
									$image1 = imagecreatefromjpeg($row2["domainURL"]."/".$row['propertyID']."_".$row2["imageName"]."_thumbnail.jpg");
							  		$size = getimagesize($row2["domainURL"]."/".$row['propertyID']."_".$row2["imageName"]."_thumbnail.jpg");
								 }
							   ELSE
							   {
									$image1 = imagecreatefromjpeg('images/awaiting_small.jpg');
									$size = getimagesize('images/awaiting_small.jpg');
							   }
							   $dest_x = $size[0] - $watermark_width - 5;  
							   $dest_y = $size[1] - $watermark_height - 5;

							   imagecopymerge($image1, $watermark, $dest_x, $dest_y, 0, 0, $watermark_width, $watermark_height, 100);
							 header("Content-Type: image/jpeg");				     imagejpeg($image1);			 		 imagedestroy($image1);  
imagedestroy($watermark);
