Fix Arras-theme timthumb bug on Windows

Have searched quite for some hours but I got finally a great solution.
You may find original post Here.

Here a short summary:
1.Edit file timthumb.php location: wp-content/themes/arras-theme/library
2.Go to line 370 -(text say: Use PECL fileinfo …)
3.uncommnet following code lines:

// if (function_exists('finfo_open')) {
	//		$finfo = finfo_open(FILEINFO_MIME);
	//		$mime_type = finfo_file($finfo, $file);
	//		finfo_close($finfo);
	//	}

add following:

$file_cmd = "file -ib \"$file\"";
      exec($file_cmd, $exec_output);
      $mime_type = $exec_output[0];

4. Save the file.

That worked for me. Hope it does for you too.
