Not sure of the question here .  It's as simple as checking to see if there is enough space in flash for your new image, do a "dir flash: " . Is the reported free space bigger than the image size you are trying to put on ? If no then you will have to delete at least 1 image to make room for the new image.Then issue "copy tftp flash: "  , it will ask you your address of the tftpserver , input , it will then ask you the name of the image  just copy and paste the name of the image in there and hit enter a couple of times and it should go if there is enough space in flash which verified with the "dir flash:  command.   The image name you posted is not a valid imagename , check the imagename and try to download the valid imagename again.
