Start with this Tutorial http://www.phpfreaks.com/tutorial/php-add-text-to-image.  It's a little dated, but I don't think much has changed.  There are also some pretty good script samples in the manual on imagettftext.

here is what i tried but no output

 

$image_path = "watermark.png";
function watermark_image($oldimage_name, $new_image_name){
    global $image_path;
    list($owidth,$oheight) = getimagesize($oldimage_name);
    $width = $height = 500;    
    $im = imagecreatetruecolor($width, $height);
    $img_src = imagecreatefromjpeg($oldimage_name);
    imagecopyresampled($im, $img_src, 0, 0, 0, 0, $width, $height, $owidth, $oheight);
    $watermark = imagecreatefrompng($image_path);
    list($w_width, $w_height) = getimagesize($image_path);        
    $pos_x = $width - $w_width;
    $pos_y = $height - $w_height;
    imagecopy($im, $watermark, $pos_x, $pos_y, 0, 0, $w_width, $w_height);
    imagejpeg($im, $new_image_name, 100);
    imagedestroy($im);
    unlink($oldimage_name);
    return true;
}

if(isset($_GET['id']))
{
    $qry = "SELECT * FROM tbl_emp where id=".$_GET['id'];
    $result = mysql_query($qry);
    $row = mysql_fetch_array($result);
    
    if($_SERVER["REQUEST_METHOD"] == "POST")
    {
        $name = $_POST["name"];
        IF($_FILES['file']['name']!='')
        {
                 $file='../uploads/profiles/'.$row['image'];
                 @unlink($file);
                    $tmp_name = $_FILES["file"]["tmp_name"];
                 $namefile = $_FILES["file"]["name"];
                 $ext = end(explode(".", $namefile));
                 $image_name=time().".".$ext;
                 $fileUpload = move_uploaded_file($tmp_name,"../uploads/profiles/".$image_name);
                 watermark_image($namefile, $image_name);
        }
        else
        {
                $image_name=$row['image'];
        }
         $sqlAdd ="update  tbl_emp set name='".$name."', image='".$image_name."'  where id=".$_GET['id'];

imagecopymerge()

 

Forgot the link to watermark example.

So you are looking to merge two images.

 
function watermark_image($oldimage_name, $new_image_name=null,$watermark){
 
    //global $image_path; //don't use global, as it leads to hard to maintain code.
 
    list($owidth,$oheight) = getimagesize($oldimage_name);
 
    $width = $height = 500;    //this should be set as an option for code reusability.
//create main image.
    $im = imagecreatetruecolor($width, $height);   
    $img = imagecreatefromjpeg($oldimage_name); 
    imagecopyresampled($im, $img, 0, 0, 0, 0, $width, $height, $owidth, $oheight);
    //create watermark image.
    $img_src = imagecreatetruecolor($width,$height);
    $wm = imagecreatefrompng($watermark);
    list($wmWidth,$wmHeight) = getimagesize($watermark);
    imageAlphaBlending($img_src, false);
imageSaveAlpha($img_src, true);
imagecopyresampled($img_src,$wm,0,0,0,0,$width,$height,$wmWidth,$wmHeight); 
//merge the images, we will use imagecopy() instead of imagecopymerge() because we don't need to set trans.
imagecopy($img, $img_src, 0, 0, 0, 0, $width,$height);
//if there is a new image name, save the image.
    if(!empty($new_image)) {
imagejpeg($img,$new_image_name,100);
imagedestroy($im); 
return true;
} else { //if there isn't a new image name, output the image.
imagejpeg($img,null,100);
imagedestroy($im); 
return true;
}
return false;
}
//set content header.
header('Content-Type: image/jpeg');
//call and output the function. (since we didn't send an image name.)
watermark_image($image_path.$image, null,$image_path.$watermark);

This is a watermarking function that I built and use.

// $wm is the watermark image you want to use
// $img is the image to watermark
// $xy should be an array of x and y coordinates - $xy['x'] = 150 $xy['y'] = 40
// placement defaults to center if $xy is not supplied
// $dest woudl be a place to save the file if you are not displaying the new image directly to the browser.
function watermarkImage($wm, $img, $xy = NULL, $dest = NULL)
{
	$watermark = imagecreatefrompng($wm);
	$wm_src = getimagesize($wm);
	$source = getimagesize($img);
	$mime = $source['mime'];
	
	if($mime === 'image/jpg')
	{$src = imagecreatefromjpeg($img);}
	elseif($mime === 'image/jpeg')
	{$src = imagecreatefromjpeg($img);}
	elseif($mime === 'image/pjpeg')
	{$src = imagecreatefromjpeg($img);}
	elseif($mime === 'image/png')
	{$src = imagecreatefrompng($img);}
	elseif($mime === 'image/gif')
	{$src = imagecreatefromgif($img);}

	$x = ($xy !== NULL) ? $xy['x'] : floor(($source[0] / 2) - ($wm_src[0] / 2));
	$y = ($xy !== NULL) ? $xy['y'] : floor(($source[1] / 2) - ($wm_src[1] / 2));
	
	imagecopy($src, $watermark, $x, $y, 0, 0, imagesx($watermark), imagesy($watermark));
	imagealphablending($src, false);
	imagesavealpha($src, true);

	if($mime === 'image/jpg')
	{
		if($dest !== NULL)
		{ imagejpeg($src, $dest, 95); }
		else
		{
			header('Content-Type: image/jpeg');
			imagejpeg($src);
		}
	}
	elseif($mime === 'image/jpeg')
	{
		if($dest !== NULL)
		{ imagejpeg($src, $dest, 95); }
		else
		{
			header('Content-Type: image/jpeg');
			imagejpeg($src);
		}
	}
	elseif($mime === 'image/pjpeg')
	{
		if($dest !== NULL)
		{ imagejpeg($src, $dest, 95); }
		else
		{
			header('Content-Type: image/jpeg');
			imagejpeg($src);
		}
	}
	elseif($mime === 'image/png')
	{
		if($dest !== NULL)
		{ imagepng($src, $dest); }
		else
		{
			header('Content-Type: image/png');
			imagepng($src);
		}
	}
	elseif($mime === 'image/gif')
	{
		if($dest !== NULL)
		{ imagegif($src, $dest); }
		else
		{
			header('Content-Type: image/gif');
			imagegif($src);
		}
	}

	imagedestroy($src);
}

issue solver :-D

 

all i had to do was first upload the image then watermark

 

                 $fileUpload = move_uploaded_file($tmp_name,"../uploads/profiles/".$image_name);
                  $image_name=time().".".$ext;
                 watermark_image($tmp_name,"../uploads/profiles/".$image_name);
