Hi,
Sorry we have never tried using getimagesize on .swf so we won't be able to help you much. You can report this issue to PHP Bug or GD Team as its related to PHP Extension. Before reporting a bug there, have a look at this post.

----------------------------------------------------------------------
PHP Blob Data As File Stream v1.0 (C) 2012 Alex Yam <alexyam@live.com>
This code is released under the MIT License.
----------------------------------------------------------------------
[Summary]
A simple class for PHP functions to read and write blob data as a file
using a stream wrapper.
Particularly useful for running getimagesize() to get the width and
height of .SWF Flash files that are stored in the database as blob data.
Tested on PHP 5.3.10.
----------------------------------------------------------------------
[Usage Example]
//Include
include('./blob_data_as_file_stream.php');
//Register the stream wrapper
stream_wrapper_register("BlobDataAsFileStream", "blob_data_as_file_stream");
//Fetch a .SWF file from the Adobe website and store it into a variable.
//Replace this with your own fetch-swf-blob-data-from-database code.
$swf_url = '[url=http://www.adobe.com/swf/software/flash/about/flashAbout_info_small.swf]http://www.adobe.com/swf/software/flash/about/flashAbout_info_small.swf[/url]';
$swf_blob_data = file_get_contents($swf_url);
//Store $swf_blob_data to the data stream
blob_data_as_file_stream::$blob_data_stream = $swf_blob_data;
//Run getimagesize() on the data stream
$swf_info = getimagesize('BlobDataAsFileStream://');
var_dump($swf_info);
----------------------------------------------------------------------
[Usage Output]
array(5) {
[0]=>
int(159)
[1]=>
int(91)
[2]=>
int(13)
[3]=>
string(23) "width="159" height="91""
["mime"]=>
string(29) "application/x-shockwave-flash"
}
