Loading a .bin IOS on a cisco 3620

Hello, Hopefully this will be a quick and easy answer - an answer which is eluding me at the moment. How can I load a new IOS to a Cisco 3620 without attaching it to a network first? I am using Putty for the local telnet session (com3), and I have both Filezilla and wsftp installed on my laptop for FTP use. I don't have an external flash memory card. I would just like to take the .bin file which is on my laptop and send it to the router... can this be done locally using what I have? Thanks for the help!
