You need a script to return the image, and you need to
pass the proper parameter from the calling page...
======= image.php ==========
<?php
// check that param exists
if (!isset($img)) {
// alternatively, you could set img to
// point to an 'error, not found' image
// from your database...
die("Error: 'img' parameter not set");
}
// hacker prevention...
$img = (int) $img;
// connect to the database
$conn = ibase_pconnect("host:dbase", "usr", "pwd")
or die("Error: ".ibase_errmsg());
// query for image
$query = "SELECT img_contents "
."FROM imgtable WHERE id=$img";
$res = ibase_query($conn, $query);
// make sure that exactly one result was returned
$num_returned = ibase_num_fields($res);
if ($num_returned == 0)
die("Error: specified image $img not found");
if ($num_returned > 1)
die("Error: $num_returned images found for $img");
// return image
// if you kept an image-type field in your
// database, you could store and retrieve
// various image types - gif, jpeg, bmp, png,
// swf, svg, etc...
header("Content-Type: image/gif");
$row = ibase_fetch_object($res);
echo $row->img_contents;
?>
