Answer 1

You need to wrap it in an img tag.

echo "<img src=\"$image\">";

To display several images

<?php

$servername="localhost";
$username="root";
$conn= mysql_connect($servername,$username)or die(mysql_error());
mysql_select_db("ek",$conn);//EK is my Database
$sql="select Pics from images";
$result=mysql_query($sql,$conn) or die(mysql_error());
$i=0; 
$display_num =4;
while($row = mysql_fetch_assoc($result) && $i++ < $display_num){
  $image = $row['Pics'];
  echo "<img src=\"$image\">";
}

 ?>

If you wish to display an image in an HTML page, you can construct the image tag like this:

<img src="<?php echo $image; ?>" />

If you are attempting to obscure the location of an image and serve it via the PHP script, your image tag will look something like this:

<img src="yourscript.php" />

and you can modify your script to open and output the file:

$image = $row['Pics'];
header("Content-Type: image/jpg");
readfile( $image );

If $row['Pics'] contains the path to the image, then you'll need to translate that into an image reference to direct the browser to that path. Something like this:

<img src="<?php echo $image; ?>" />

Note that "path" can mean something entirely different here. If it's a server-side fully qualified path, you'll want to translate it into an application-relative path usable by the browser. Something that begins with /usr/web/something/blah/ won't be useful to the browser.
