html display images without intermediate file

[paul@xxxxxxxxxx]

Bonjour

code working :
$link = pg_Connect("host=localhost dbname=... user=... password='...'");
$res = pg_query($link, "select miniature  from photo ");
$numrows = pg_numrows($res);
for($ri = 0; $ri < $numrows; $ri++) {
$row = pg_fetch_array($res, $ri);
$img =  pg_unescape_bytea($row['miniature']);
$fln = "toto".$ri.".jpeg";
file_put_contents($fln, $img);
echo "<img src=''/>";
}

How to do without the  intermediate file $fln ?

Merci
