I'm using a flash uploader and the problem is that flash upload file with application/octet-stream for every kind of file! So if you want to use all the image stuff I find a small hack for your class... Here it is an tell me what do you think about it. Maybe good for a 0.26!! I test it on macosx, it works great (it use the shell). If none of the 3 function works, I don't know how to get the right mime-type... Here is my code, juste inserted before // if the file is an image, we gather some useful data

if (array_key_exists($this->file_src_mime, $this->image_supported))...
//Maybe the file come from flash so the mime-type is application/octet-stream even for an image
if($this->file_src_mime == 'application/octet-stream') {
  if (function_exists('mime_content_type')) { //Double check the mime-type with magic-mime if avaible
    $this->file_src_mime = mime_content_type($this->file_src_pathname);
  } elseif (strlen($mime=@shell_exec("file -bi ".escapeshellarg($this->file_src_pathname)))!=0) { //Using shell if unix an authorized
    $this->file_src_mime = trim($mime);
  } else { //Check if fileinfo extension is available
	if (!extension_loaded("fileinfo.so") && !dl("fileinfo.so")) {
	  return false;
	} else {
	  if (function_exists('finfo_open')) {
        $f = finfo_open(FILEINFO_MIME);
        $mime = finfo_file($f, $this->file_src_pathname);
        finfo_close($f);
        $this->file_src_mime = $mime;
      } elseif (class_exists('finfo')) {
        $f = new finfo( FILEINFO_MIME );
        $this->file_src_mime = $info->file($this->file_src_pathname);
      }
    }
  }
}
