Image Uploader Modification

[Grok 🤖]

I have an image uploader which is causing images to stretch when they are being resized, which i do not want.

 

I need the image to be resized 3 times and moved into 3 different folders, but i do not want the image to be scaled up if it is too big.

 

Here is the code i'm working with;

 

<?php

include('include/session.php');
if($session->logged_in){

ini_set("session.gc_maxlifetime","10800");
ini_set("upload_max_size","4194304");
$default = $_POST["default"];
$username = $session->userinfo['username'];

if(isset($_FILES))
{
$fileName = $_FILES["uploadfile"]["name"];
// get the file extension first
$ext = substr(strrchr($fileName, "."), 1);
// make the random file name
do{
$randName = md5(rand() * time());
$pass = "$randName.$ext";
$Check = (file_exists("upimg/$pass") || file_exists("thimg/$pass") || file_exists("avimg/$pass"));
}while( $Check );
$uploadedfile = $_FILES["uploadfile"]["tmp_name"];

list($width,$height)=getimagesize($uploadedfile);

$newwidth1=600;
$newwidth2=180;
$newwidth3=100;
$newheight1=($height/$width)*600;
$newheight2=($height/$width)*180;
$newheight3=($height/$width)*100;

switch($_FILES['uploadfile']['type'])
{
case "image/gif":
	$src = imagecreatefromgif($uploadedfile);//Create from GIF!
	$type = "gif";
break;
case "image/jpg":
case "image/jpeg":
	$src = imagecreatefromjpeg($uploadedfile);//Create from JPEG!
	$type = "jpg";
break;
}
#1
//$src = imagecreatefromjpeg($uploadedfile);//Create from JPEG!
$tmp1=imagecreatetruecolor($newwidth1,$newheight1);
imagecopyresampled($tmp1,$src,0,0,0,0,$newwidth1,$newheight1,$width,$height);
$filename = "upimg/$pass";// . $_FILES["uploadfile"]["name"];
if($type == "gif")
{
imagegif($tmp1,$filename,100);
}elseif($type == "jpg"){
imagejpeg($tmp1,$filename,100);
}
imagedestroy($src);

#2
$tmp2=imagecreatetruecolor($newwidth2,$newheight2);
imagecopyresampled($tmp2,$tmp1,0,0,0,0,$newwidth2,$newheight2,$newwidth1,$newheight1);
$filename = "thimg/$pass";// . $_FILES["uploadfile"]["name"];
if($type == "gif")
{
imagegif($tmp2,$filename,100);
}elseif($type == "jpg"){
imagejpeg($tmp2,$filename,100);
}
imagedestroy($tmp1);

#3
$tmp3=imagecreatetruecolor($newwidth3,$newheight3);
imagecopyresampled($tmp3,$tmp2,0,0,0,0,$newwidth3,$newheight3,$newwidth2,$newheight2);
$filename = "avimg/$pass";// . $_FILES["uploadfile"]["name"];
if($type == "gif")
{
imagegif($tmp3,$filename,100);
}elseif($type == "jpg"){
imagejpeg($tmp3,$filename,100);
}
imagedestroy($tmp2);
imagedestroy($tmp3);

$name = $_FILES["uploadfile"]["name"];
}}

# $query = "INSERT INTO track9_userphotos (pictureurl, username, caption) VALUES('$pass', '$username', '$caption')";
# mysql_query($query) or die(mysql_error());

if ( $default == 1 ) {
mysql_query("UPDATE ".TBL_USERS." SET photo = '$pass' WHERE username = '$username'");
} else { echo ""; }


?>
<h8>Your Uploaded Picture</h8><p><div id='header2'>
<br><br>
<table border="0" width="700" cellspacing="0" cellpadding="0">
<tr>
	<td width="200" valign="top">
	<p align="center"><? echo "<img src='thimg/$pass'>"; ?></p>
	<p></td>
	<td>
	<p align="center">  
<p align="center"> </p>

	<p></td>
</tr>
</table>
</div>

heres what i use

 

<?php

//set max height and width for bgimage
$bg_height = 900;
$bg_width  = 900;
$bg_pixels = 900;

//set max height and width for smimage
$sm_height = 100;
$sm_width  = 100;
$sm_pixels = 100;

//big
$new_bg_height=($height_orig/$width_orig)*$bg_pixels;
$tmp_bg=imagecreatetruecolor($bg_width,$new_bg_height);
//small
$new_sm_height=($height_orig/$width_orig)*$sm_pixels;
$tmp_sm=imagecreatetruecolor($sm_width,$new_sm_height);
// these lines actually do the image resizing, copying from the original
// image into the $tmp image
	imagecopyresampled($tmp_bg,$src_bg,0,0,0,0,$bg_width,$new_bg_height,$width_orig,$height_orig);
	imagecopyresampled($tmp_sm,$src_sm,0,0,0,0,$sm_width,$new_sm_height,$width_orig,$height_orig);

//BIG: write the resized image to disk.
//$filename contains the path and the image name
$filename_bg = "../../../photos/misc/bigphotos/". $bg_file;
//0-100 is quality setting
imagejpeg($tmp_bg,$filename_bg,100);

//SMALL: write the resized image to disk.
//$filename contains the path and the image name
$filename_sm = "../../../photos/misc/smallphotos/". $sm_file;
//0-100 is quality setting
imagejpeg($tmp_sm,$filename_sm,100);
?>

 

i dont really see a difference between ours at a quick glance but this does work (only for a horizontal image though)
