getimagesize() [No such file or directory]

[webking2003]

in "qqUploadedFileXhr" ho creato validate() in questo modo:

function validate(){
 $name = $this->getName();
 $path = pathinfo($this->getName());
      
 $imageInfo = getimagesize($path.'/'.$this); 
 if($imageInfo['mime'] != 'image/gif' && $imageInfo['mime'] != 'image/jpg' && $imageInfo['mime'] != 'image/bmp'&& $imageInfo['mime'] != 'image/png'){  
  return false;
 }
} 

ma in questo modo ricevo errore :

Catchable fatal error: Object of class qqUploadedFileXhr could not be converted to string

sulla riga:
$imageInfo = getimagesize($path.'/'.$name);

credo di esserci vicino..
