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

However when my images grow too large (1024x768), the image data coming out of the SOAP request appears to be truncated. For example, instead of being 169,048 bytes, it is 166,448 bytes.
