Displaying Image uploaded to mysql PHP - need to display string - php

Question

I was trying to figure out how to upload an image into mysql then display it. I got the uploading part set. The problem I am have is displaying it. When I go to display it does one of the following:
Displays no image but only has a little image icon 10x10px image on top left
Displays the whole string of the image and then properly renders the image.
When I remove/comment out the echo $contentIMG statement, nothing displays.
<?php
include 'connections/conn.php';
error_reporting(E_ALL);
// some basic sanity checks
if(isset($_GET['id']) && is_numeric($_GET['id'])) {
$contentIMG = $row_Recordset1['content'];
echo $row_Recordset1['content'];
//echo $contentIMG;
// set the header for the image
//header("Content-type: image/jpeg");
header("Content-type: image/jpeg\n\n");
echo "where is the image #1<br>";
//echo '<img src="data:image/jpeg;base64,'.$contentIMG.'"/>';
echo "where is the image #2<br>";
echo '<img src="data:image/jpeg;base64,'.base64_encode( $contentIMG ).'"/>';
if (isset($contentIMG)){
//echo '<img src="data:image/jpg;base64,'.base64_encode($contentIMG).'" />';
}
//echo mysql_result($result, 0);
// close the db link
mysql_close($result);
}
else {
echo 'Please use a real id number';
}
echo "break <br>";
$img=base64_encode($row_Recordset1['content']);
?>
I looks like this

I may be wrong but I think that when you set your header Content-type to image/jpeg, you should just return the image data (assuming it is stored as a blob in your database)
<?php
header('Content-type: image/jpeg');
echo $contentIMG;
?>
Your code should look like this:
<?php
include 'connections/conn.php';
error_reporting(E_ALL);
// some basic sanity checks
if(isset($_GET['id']) && is_numeric($_GET['id'])) {
$contentIMG = $row_Recordset1['content'];
header('Content-type: image/jpeg');
echo $row_Recordset1['content'];
// close the db link
mysql_close($result);
}
else {
echo 'Please use a real id number';
}
?>
