Hello,

I have narrowed my problem down more.  Firstly, the truncation is happening for \
base64 images that are as small as 2,010 bytes.  Further, the data being passed into \
the function "submitSighting" appears to be fine.  That is, I compared the length of \
the $photovideo argument within submitSighting on the SOAP server with the length of \
the image on the client side, before it is sent to the SOAP server, and they are \
identical.  So I am lead to believe that the base64_encode function producing strings \
that are not the same as those my client are producing.

My solution for now is to just rip the original client-formatted base64 \
representation of the image out of the request as follows:

if (preg_match('/<photovideo xsi:type="xsd:base64Binary">(.*)<\/photovideo>/ims', \
$request, $matches)) {  $myPhotoVideo = $matches[1];
}

This is less than ideal, and opens me up to potential security vulnerabilities, but \
it works for now.

If anyone has any advice, I'd love to hear it.

Best,

Brian
