Thank you in advance,

copy flash:/(ios image filename) tftp

If it is in a folder then you will need the folder name/filename and then a destination (tftp).

The rest should be self evident.

Always check the MD5 of the image after it has transferred. Run the following command on the source device, get the MD5 and run it again on the destination device and verify against source MD5 output to ensure there is not any corruption of the image.

verify /md5 flash:c2811-advipservicesk9-mz.124-4.bin

Good article here on how to copy from one device to another.

first of all you need to make a connection between your switch and computer, then follow the below commands

conf t
vlan 22
name mgt
int vlan 22
ip add 192.168.1.1.100 255.255.255.0
int g1/0/12
switchport access vlan 22
--------------------
dir flash:
copy flash: tftp: ....

Another possible option is to enable small services so the Cisco device, itself, can act as tftp or FTP server.  Then you can "pull" an IOS file from the device using a tftp or FTP client.

PS:

Also, some Cisco devices support USB or CF cards.  You can copy an IOS to one of those and move it to another host.
