why imagecreatefromjpeg() function is not opening the file from the folder - php

Question

I want to resize the image file after upload with the help of imagecreatefromjpeg function but this function is unable to access the file from the folder as it's throwing the error i.e., **
imagecreatefromjpeg(): gd-jpeg: JPEG library reports unrecoverable
error: in D:\xampp\htdocs\resize\index.php
** but file is uploaded & I wrote the following code.
<form method="post" enctype="multipart/form-data">
<input type="file" name="f1">
<input type="submit" name="btn" value="Upload">
</form>
<?php
ini_set("memory_limit","256M");
if(isset($_POST['btn']))
{
if(move_uploaded_file($_FILES['f1']['tmp_name'], "images/".$_FILES['f1']['name']))
{
$filename = "images/".$_FILES['f1']['name'];
$original_info = getimagesize($filename);
$original_w = $original_info[0];
$original_h = $original_info[1];
echo "<img src =$filename>";
if( ini_get('allow_url_fopen') ) {
// it's enabled, so do something
$original_img = imagecreatefromjpeg($filename);
$thumb_w = 100;
$thumb_h = 60;
$thumb_img = imagecreatetruecolor($thumb_w, $thumb_h);
$thumb_filename = "new.jpg";
imagecopyresampled($thumb_img, $original_img,
0, 0,
0, 0,
$thumb_w, $thumb_h,
$original_w, $original_h);
imagejpeg($thumb_img, $thumb_filename);
imagedestroy($thumb_img);
imagedestroy($original_img);
}
}
}
?>

You must make sure of the type of file.
<?php
$type = exif_imagetype($filename);
// types 1=>gif, 2=>jpg, 3=>png, 6=>bmp
switch ($type) {
case 1 : $img = imageCreateFromGif ( $src );break;
case 2 : $img = imageCreateFromJpeg( $src );break;
case 3 : $img = imageCreateFromPng ( $src );break;
case 6 : $img = imageCreateFromBmp ( $src );break;
}
// or if you cannot use exif_imagetype
// you can use getImageSize
$type = getImageSize($filename);
switch ($type) {
case 'image/gif' : $img = imageCreateFromGif ( $filename ); break;
case 'image/jpeg' : $img = imageCreateFromJpeg( $filename ); break;
case 'image/png' : $img = imageCreateFromPng ( $filename ); break;
case 'image/bmp' : $img = imageCreateFromBmp ( $filename ); break;
}
//// than you can create new file with resize or crop...
