Problem when trying to display image from database

[eluser]TheFuzzy0ne[/eluser]
These functions might work a little better:

Code:

function displayimage($Id=FALSE)
{
    if ($Id))
    {
        $image = $this->MMarches->getImage($Id);
        header("Content-type: image/jpeg");
        print($image);
    }        
}

function getImage($Id)
{
    $data = '';
    $Q = $this->db->query("SELECT MA_PHOTO FROM GERICO.REF_MARCHES WHERE MA_ID=".$Id);
    if ($Q->num_rows())
    {
        $data = $Q->row_array();
        $data = $data['MA_PHOTO']
        $Q->free_result();  
    }
    return $data;
}

The above code is untested.
