I have some scripts used to upload gifs. The form has the right enctype, and the script looks like:

==
list($filename, $fileext) = explode(".", basename($upfile_name));

$file = $filename . '.' . $fileext;

if (file_exists($DOCUMENT_ROOT . '/dbimages/' . $file)) {
	$i = 0;
	while(file_exists($DOCUMENT_ROOT . '/dbimages/' . $file)) {
		$i++;
		$file = $filename . '(' . $i . ').' . $fileext;
	}
}


$rfp = fopen($upfile, 'r');
$wfp = fopen($DOCUMENT_ROOT . '/dbimages/' . $file, 'w');
fwrite($wfp, fread($rfp, filesize($upfile)));
fclose($wfp);
fclose($rfp);
==

But the uploaded file is missing a few bytes. Check out the screenshot below. It's only about 5 bytes missing, but that doesn't help a browser trying to render the image.

I downloaded a windows binary about 2 weeks ago and installed it on winxp/apache. If you need any other info, just ask.
