You have at least one parse error right on the first if statement (check out the extra semi-colon).

And you're missing a semi-colon on the line after that.

Here is a version that should parse:

<?php 
if(($page=="main")||($page=="comments")) { 
 $path = $fbimage[1]; 
 $verbose = "0"; 
 $data = read_exif_data_raw($path, $verbose); 
 $fbexposure = $data['SubIFD']['ExposureTime']; 
 $fbexposure = reduceExif($fbexposure); 
 $fbexposure = "$fbexposure sec"; 
 $fbfocallength = $data['SubIFD']['FocalLength']; 
 $fbaperture = $data['SubIFD']['FNumber']; 
 $fbcamera = trim($data['IFD0']['Make']; 
 $fbflash = $data['SubIFD']['Flash']; 
 $fbtaken = $data['SubIFD']['DateTimeOriginal']; 
 $fbiso = $data['SubIFD']['ISOSpeedRatings']); 
} 
$tags += array("<#fbcamera#>" => isset($fbcamera) ? $fbcamera : "", 
 "<#fbflash#>" => isset($data["Flash"]) ? (bindec($data["Flash"]) ? "On" : "Off") : "", 
 "<#fbfocallength#>" => isset($fbfocallength) ? $fbfocallength : "", 
 "<#fbexposure#>" => isset($fbexposure) ? $fbexposure : "", 
 "<#fbiso#>" => isset($fbiso) ? $fbiso : "", 
 "<#fbaperture#>" => isset($fbaperture) ? $fbaperture : "", 
 "<#fbtaken#>"=> isset($fbaperture) ? $fbaperture : ""); 
?>

thanks for your help
here what i'm running right now...
need to optimize the code but right it's running fine.
get the library here:
http://www.jakeo.com/software/exif/index.php
then use this php script
<?php
// fb_exif Extension
// by Donald Tetto (with modifications by James Yencken)
// http://folderblog.tetto.org/
include ("path2library/exif.php");
if(($page=="main")||($page=="comments")) {
$path = $fbimage[1];
$verbose = "0";
$data = read_exif_data_raw($path, $verbose);
$fbexposure = $data['SubIFD']['ExposureTime'];
$fbfocallength = $data['SubIFD']['FocalLength'];
$fbaperture = $data['SubIFD']['FNumber'];
$fbcamera1 = trim($data['IFD0']['Make']);
$fbcamera2 = trim($data['IFD0']['Model']);
$fbcamera = "$fbcamera1 - $fbcamera2";
$fbflash = $data['SubIFD']['Flash'];
$fbtaken =$data['SubIFD']['DateTimeOriginal'];
$fbtaken = date($fbtaken,"d/m/Y" - "H:i");
/* $fbiso = $data['SubIFD']['ISOSpeedRatings'];
$fbwhitebalance = $data['SubIFD']['WhiteBalance'];
$fbexposurecomp = $data['SubIFD']['ExposureBiasValue']; */
}
