Pathway to desk top please

I am trying to mount minepeon on my sd card. The mine peon image is on my desktop and the ikon says MinePeon-0.2.1.img I tried writing this:

sudo dd bs=1m if=/path/to/minepeon-0.2.2.1.img of=/dev/disk1

But it says there is no file like this what am I doing wrong please?

pc3:~ raspberrypi$ sudo dd bs=1m if=/users/raspberry pi/desktop/MinePeon-0.2.1.img of=/dev/disk1
Password:
dd: unknown operand pi/desktop/MinePeon-0.2.1.img
pc3:~ raspberrypi$

The path to a file on the desktop looks like this:
/Users/_your_user_/Desktop/_filename_
where _your_user_ is replaced by the correct value, etc.

By the way, you can avoid typos by typing the dd command up to the point where the in-file (if) name goes, and dragging the file icon from the desktop to the Terminal window - the full path and filename will be filled in for you.
