In the sample code the default is the record_id that corresponds back to the id of the row with the image blob field.

This is in the main page - <? printf("<p><img src=\"image-src.php?id=$id\" alt=\"hotspot images\">%s</p>", $row["text"]); ?> and this is in a new included page - <? if($_GET['id']) { $id = $_GET['id']; $query = "select * from hotspots where id=$id"; $result = @MYSQL_QUERY($query);
$data = @MYSQL_RESULT($result,0,"image"); $type = @MYSQL_RESULT($result,0,"type");
Header( "Content-type: $type"); echo $data; }; ?> The database connection statements are in an include file called at the top of the main page. In the first statement shown above the alt text for the image appears on the web page just fine, the image itself shows a broken image icon. FWIW, I have the image stored in the database in a blob field, is that correct? -- Chip
