Hm I'm using vgrabbj, lftp, cron and a few very short shell scripts to
grab the picture and upload it to my ftp server with ftps.

Donno if it helps you ...

crontab line:
-------------
*/5 * * * * /home/sven/camstuff/grabimage.sh


The grabimage.sh script:
------------------------
#!/bin/bash
#get a current img from cam
vgrabbj -i sif -f /home/sven/camstuff/current.jpg -d /dev/video0 -t /home/sven/camstuff/FreeMonoBold.ttf -m 75 -a 3 -n > /dev/null 2>&1

#cp current img into the archiv
cp /home/sven/camstuff/current.jpg /home/sven/camstuff/archiv/img-$(date +%Y%m%d%k%M|sed -e 's/ //g').jpg

#upload current img
lftp -f /home/sven/camstuff/ftpscript > /dev/null 2>&1


The ftpscript for lftp:
-----------------------
open -u user,pass my.server.de
put /home/sven/camstuff/current.jpg -o current-tmp.jpg
mv current-tmp.jpg current.jpg
quit
