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!

You will need a tftp server on your laptop in order to transfer. Solar winds has a free tftp server.

Place the IOS is the tftp root folder and then connect your laptop to the router. Connect to the router via putty (console) and configure an ip address on the interface connected to the laptop. then configure an ip address on your laptop that is in the same subnet (ex: 10.0.0.1 and 10.0.0.2).

From the router ping the laptop ip to insure connectivity. Once you have verified connectivity then follow this link to install the IOS.
