it's pretty easy to have an auto-ftp script. the first clue is to use a file called .netrc - create one in the home directory for user zaurus, and it looks like this:
machine ftp.example.com login zaurus password z4uru5
change the host, the username and the password appropriately
this makes the "ftp ftp.example.com" automatically login for you.
then you need a script which will ftp all the files for you from the card and then move them to an "old" directory, thus:
#!/bin/bash
if [ ! -d ../old ]; then
mkdir ../old
fi
cd /mnt/card/imagefolder/new
echo "type i" > /tmp/ftpcommand
ls *.jpg *.JPG | awk '{ "put " $1 }' >> /tmp/ftpcommand
ftp ftp.example.com < /tmp/ftpcommand
mv *jpg *JPG ../old
# end
this is all off the top of my head, but something similar works for me and my webcam.
