I typically create a config file that hoses the main information - for example

config.cfg containing
username
password
prompt
binary
cd data
mput *.jpg
mput *.gif
mput *.png
bye

Then create a send.bat containing:
ftp -s:config.cfg ftp.server.com

If you really want to get fancy you can then create a third batch file called start.bat with the command:
send.bat > log.txt

That will log the whole transfer to a txt file so you can check for errors.
