You could rename the file before you upload, or upload as a different name.

I don't think I have any control over how the security software writes to the FTP site, so maybe I'd need to have some script running that only copies intact files to a secondary directory... I really don't know about this one...
But then you have the problem of how to identify intact files. How long does it take to upload one file? Would a lag of double that time before the updated picture becomes visible be acceptable?

pbmtopsg3
pbmtopsg3(29 June 2001) pbmtopsg3(29 June 2001)
NAME
pbmtopsg3 - convert PBM images to Postscript with G3 fax compression
SYNOPSIS
pbmtopsg3 [--title=title] [--dpi=dpi] [filespec]
DESCRIPTION
Converts the PBM images in the input PBM file to pages in a Postscript file encoded with G3 fax compression.
If you don't specify filespec, the input is from Standard Input.
Remember that you can create a multi-image PBM file simply by concatenating single-image PBM files, so if each page is in a different file,
you might do:
cat faxpage* | pbmtopsg3 >fax.ps
OPTIONS
-title The Postscript title value. Default is no title.
-dpi The resolution of the Postscript output. Default is 72 dpi.
