 * During image upload, I get the following warning :
 * Warning: trim() expects parameter 1 to be string, array given in /wp-admin/includes/
   image.php on line 300
 * The line 300 is:
    $meta[‘iso’] = utf8_encode( trim( $exif[‘ISOSpeedRatings’] ));
 * The error is that $exif[‘ISOSpeedRatings’] can be an array, for example Array([
   0] => 200 [1] => 200 ). So the trim() function returns the warning.
