File Upload cutting images off

This is my code for uploading a thumbnail image to the server:

<?php
// WA_UploadResult2 Params Start
$WA_UploadResult2_Params = array();
// WA_UploadResult2_1 Start
$WA_UploadResult2_Params["WA_UploadResult2_1"] = array(
'UploadFolder' => "../slideshowImages/thumbs/",
'FileName' => "[FileName]",
'DefaultFileName' => "",
'ResizeType' => "4",
'ResizeWidth' => "200",
'ResizeHeight' => "200",
'ResizeFillColor' => "" );
// WA_UploadResult2_1 End
// WA_UploadResult2 Params End
?>

I have specified that I would like it to be 200 x 200 pixels in size. Once uploaded, the document is 200 x 200, but the image is always "short." Half of it is missing. Am I doing something incorrectly? I am attaching an example image.

Thank you.
