Random ouput is displayed when tranferring image data - php

Question

This is my code. The user adds an image from a previous page where it is then collected by $_FILES and processed in this page. The weird thing is, when someone adds an image, I get a large random paragraph of random numbers and symbols that is displayed on this page. I have no clue where this is from. Any thoughts?
And if you guys were curious, that form at the bottom redirects all the information to another page where is then added into the database.
<?php
$file = $_FILES['image']['tmp_name'];
if(isset($file))
{
$image_1 = file_get_contents($_FILES['image']['tmp_name']);
$image_name = $_FILES['image']['name'];
$image_size = getimagesize($_FILES['image']['tmp_name']);
}
if ($image_size===FALSE)
{
die("That is not an image. Please go back and choose and image.");
}
$title = $_POST['title'];
$author = $_POST['author'];
$isbn = $_POST['isbn'];
$price = $_POST['price'];
$location = $_POST['location'];
$class = $_POST['class'];
$description = $_POST['description'];
$contact = $_POST['contact'];
$img = $image_1;
$img_name = $image_name;
if(!$title || !$author || !$isbn || !$price || !$location || !$class ||
!$description || !$contact)
{
echo "You have not entered all the required details.<br/>"
."Please go back and try again.";
exit;
}
?>

You are getting the binary source of the image here:
$image_1 = file_get_contents($_FILES['image']['tmp_name']);
Then echoing it out in the hidden field here:
<input type="hidden" name="image" value="<?php echo $img;?>" />
That is most likely where that paragraph is coming from. Not sure why you are including it, the tmp path is all you really need.
