Getting images onto server from separate web host

i have GoDaddy shared webspace with FTP access that contains a folder with images. These images are changing every day.

Im looking for advice on what i need to do to get these images onto my server in the workplace, maybe every hour or so. The server doesnt have IIS installed is there any other way to do this?

Am i able to do a PHP script that can put all the images onto the server using the ip or something?
