This could be the issue right here. In Apache, %b is "the size of the
object returned to the client, not including the response headers." I
don't know if this is calculated from the actual bytes transferred or
the Content-Length header sent with the object. There are two
possiblities here. If the Content-Length header is used, then perhaps
you are not setting it in your PHP files. More likely, if the actual
size of the data _sent_ to the client is used, then it's very likely
that many of your visitors are clicking on a large file and then
cancelling the download. So they actually only transfer say 300MB of the
file before they give up or lose connection. This gets logged instead of
the 5GB image size you are expecting.
You could probably do some tests with this fairly easily and find out
what's written to your logs.
