thanks, but now I need to save an image as a file.
I use this code to view the image:

Code:

<?php
  Header('Content-type: image/gif');
  include("./libs/AcessaKOPP.php");
  $temp_sql = "SELECT FOTO FROM INTEGRANTE where cod_integrante=8";
  $rs =& $mdb2->query($temp_sql, array('blob'));
  $row = $rs->fetchRow();

  $blob = $row[0];
  if (!PEAR::isError($blob) && is_resource($blob)) {
    $blob_value = '';
    while (!feof($blob)) {
        $blob_value .= fread($blob, 8192);
    }
    $mdb2->datatype->destroyLOB($blob);
  }
  $rs->free();
  print($blob_value."\n");

  // here I want to save the image as a file from the value of the variable  $blob_value
?>

Use file_put_contents() or fwrite().
