For example if you use this code , you can load image from db (mysql) and display it in php5 ;)
<?php
$con =mysql_connect("localhost", "root" , "");
$sdb= mysql_select_db("my_database",$con);
$sql = "SELECT * FROM `news` WHERE 1";
$mq = mysql_query($sql) or die ("not working query");
$row = mysql_fetch_array($mq) or die("line 44 not working");
$s=$row['photo'];
echo $row['photo'];
echo '<img src="'.$s.'" alt="HTML5 Icon" style="width:128px;height:128px">';
?>
