You don't. Imagine 50 pictures saved in compressed png format and 50 pictures saved in
base64 format? Which will take more time to load? If you don't want to save the images
temporary what about this:
echo '<img src="temp/thumb.php?pic=xxx">';
thumb.php:
//get the id of the picture
$pic=(int)$_REQUEST['pic']
//load picture from database and store in $image
....
header("image/png");
echo $image;
