Hi Pierre-Alex,
The reason you are unable to TFTP an image to/from a Cisco2500 series
router is because, unlike most other platforms, it runs the IOS from
flash. If you do a "show version" on a Cisco2500 the flash will appear
as read-only and not read/write. Therefore, you will have to boot the
router into boot-mode (change the config register to 0x2101) and you
will notice now that the flash is read/write. You will now be able to
TFTP the image to flash.
I hope this helps, and if you have any problems let me know.
Cheers
Darren

It looks like the c2500 image you have is a
relocatable image, and the 4000 doesn't support
relocatable images. A relocatable image is one that
can be a different file # on flash. A non-relocatable
image has to be file 1. The 4500 is newer then the
4000 so may support relocatable images; this may be a
bootloader/bootrom version issue as well. cisco.com
will have the info though.
I know when you do a copy tftp on cisco, Pumpkin TFTP
server reports 2-3 aborted transfers before the full
tftp download. This may mean that IOS is checking the
image name or just grabbing the first few bytes of the
file to look at the headers, etc to see if its a valid
image for that router. You can try renaming the image,
etc but I'm not sure what IOS looks at exactly.
