Convert uploaded image to jpg and add logo

[phillips321]

Hi guys,

 

I have got my script working so that only GIF, PNG, BMP and JPG files can be uploaded.

 

It then saves these images to the "uploads" directory.

 

What i would like to do is automatically convert these images to jpg and also add a small logo onto the image before saving it.

 

I have heard of imagemagic but i dont really know how to use it.

 

Anyone know of any tutorials or code i can have a look through to help me?

 

Is this going to be difficult to do?

 

P.s. My existing upload code is below

<?php
$path= "uploads/".$HTTP_POST_FILES['ufile']['name'];
$quit=0;
$size= $HTTP_POST_FILES['ufile']['size'];
$type= $HTTP_POST_FILES['ufile']['type'];

if($size > 350000)
{
        echo "Your file is too large.<br>";
        $quit=1;
}

if(($type == "image/jpeg") || ($type == "image/gif") || ($type == "image/png") || ($type == "image/bmp"))
{
        if(!($quit==1))
        {
                if(copy($HTTP_POST_FILES['ufile']['tmp_name'], $path))
                {
                        echo "Successful<BR/>";
                        echo "File Name :".$HTTP_POST_FILES['ufile']['name']."<BR/>";
                        echo "File Size :".$HTTP_POST_FILES['ufile']['size']."<BR/>";
                        echo "File Type :".$HTTP_POST_FILES['ufile']['type']."<BR/>";
                        echo "Image Location: <A href=".$path.">http://forumpix.getmyip.com/".$path."</A><BR/>";
                        echo "<img src=\"$path\">";
                }
        }
        else
        {
        echo "There was an error.<br>";
        }
}
else
{
        echo "You may only upload JPG, BMP, PNG or GIF images.<br>";
        $quit=1;
}

just to note i already have GD installed on the server so if i could use that it would be handy.

 

I've been looking at this site but i'm still confused

To convert the file types, use imagecreatefromgif, imagecreatefrompng  and imagecreatefromwbmp

 

A week or so ago, someone posted code to add a watermark.

 

Found it....

<?php  

header('content-type: image/jpeg');  

$original_image = "image.jpg";

$watermark = imagecreatefrompng('watermark.png');  
$watermark_width = imagesx($watermark);  
$watermark_height = imagesy($watermark);  
$image = imagecreatetruecolor($watermark_width, $watermark_height);  
$image = imagecreatefromjpeg($original_image);  
$size = getimagesize($original_image);  
$dest_x = $size[0] - $watermark_width - 5;  
$dest_y = $size[1] - $watermark_height - 5;  
imagecopymerge($image, $watermark, $dest_x, $dest_y, 0, 0, $watermark_width, $watermark_height, 100);  
imagejpeg($image);  
imagedestroy($image);  
imagedestroy($watermark); 
?>
