Display image from MySql database in Php server - php

Question

I send an image from my Android Application to my Php server using a MySql database, but when i try to display the image in browser it doesn't work.
This is how I send the picture
String imageString=Base64.encodeBytes(this.image);
nameValuePairs.add(new BasicNameValuePair("image", imageString));
And this is how I try to display it
echo '<img src="data:image/jpeg;base64,'.base64_encode( $row['image'] ).'"/>';
I've checked and imageString in my app is different from base64_encode( $row['image']).
MySql part
$conn = new mysqli($server, $username, $password, $database);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
// sql to create table
$sql = "CREATE TABLE Posts (
id INTEGER UNSIGNED AUTO_INCREMENT PRIMARY KEY,
user VARCHAR(50) NOT NULL,
date VARCHAR(12) NOT NULL,
event VARCHAR(1000),
image BLOB
)";
if ($conn->query($sql) === TRUE) {
echo "Table Posts created successfully";
} else {
echo "Error creating table: " . $conn->error;
}
$conn->close();
$con = mysql_connect($server, $username, $password) or die ("Could not connect: " . mysql_error());
mysql_select_db($database, $con);
$user = $_POST['user'];
$date = $_POST['date'];
$event = $_POST['event'];
$image = $_POST['image'];
echo "Test";
$sql = "INSERT INTO Posts (user, date, event,image) ";
$sql .= "VALUES ('$user','$date', '$event', '$image')";
if (!mysql_query($sql, $con)) {
die('Error: ' . mysql_error());
} else {
echo "Insert success";
}
mysql_close($con);
if ($result->num_rows > 0) {
// output data of each row
while($row = $result->fetch_assoc()) {
echo $row["user"]. $row["date"]. $row["event"]. "<br>";
echo '<img src="data:image/jpeg;base64,'.base64_encode( $row['image'] ).'"/>';

Your Java code is doing a Base64 encode of the image before sending it to the server. You do not need to encode it a second time when you go to display it. The result is a base64 encoded string of a base64 encoded string, which isn't what you want to do.
Try this instead:
echo '<img src="data:image/jpeg;base64,' . $row['image'] . '"/>';
