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, $img);
echo "<img src='".$fln."'/>";
}
How to do without the  intermediate file $fln ?
Merci

The src in the img tag should point to a script that fetches the image, see header() in the PHP manual.

But you probably should not do that, because it is very slow and loads the database up with tasks that it should not do.
Keep images as files on disk, that is *much* faster.
