online Picture leech bot

Hello Computer guys, I need some advice.

There is a website at
http://ourplanet.ath.cx/satellite/ that shows a
picture of the earth from space with earthquake,
volcano, satillite positions and night/day time
shades.  This picture is updated every 20 minutes.  

I would like to save a copy of each picture every 20
minutes so that I can create a animation from them. 
Does anyone know how I can do this?  Is there a
program out there where you can set it to download and
save a picture from a certain website and dedicate it
to continue doing so every 20 minutes?

I'd really appreciate it if someone can help me out. 
Someone told me, look up "WGET" on google, but, I
didn't understand how to do what I wanted with that
program.

Thanks
Eduardo Hernandez
