fread will not add the code to display the picture, it only shows the data that is in the file... What you want to do is display a page with an img tag, and its source pointing to your image file, or serve it using php:
echo"<div style='width: 15%; height:10%; position:relative; top:22%; left:20%'/><img src='uploads/foto4.JPG'/></div>";
// Or
echo"<div style='width: 15%; height:10%; position:relative; top:22%; left:20%'/><img src='uploads.php?f=foto4.JPG'/></div>";
If you use the second solution, see it points to a php file... All your uploads would be handled by your PHP that way if you want to control access or other stuff...
//uploads.php
header('Content-Type: image/jpeg'); // We are serving a jpeg.
readfile('uploads/'.$_GET['f']);
EDIT:
Finally, one could use the data URI scheme to show the picture inline, this method would fit perfectly for your code snippet but might not be required as not all browsers support it (but all majors do). Read more at http://www.websiteoptimization.com/speed/tweak/inline-images/
<?php
$image = fopen('upload/foto4.JPG', 'rb');
$Data = fread($image,filesize('$image'));
fclose($image);
echo'<div style="width:15%;height:10%;position:relative;top:22%;left:20%"/><img src="data:image/jpeg;base64,'.base64_encode($Data).'"/></div>';
?>
