You see the problem is that I want to transfer my pictures back to my sd card and I try to view my sd card by my canon camera and I didn't see any pics I taken from copying the pics on the computer.so how can i copy my pics from my computer to sd card then in order to view it on my canon camera.

If you only copied the pictures they should still be on the SD card. If you moved them then they will be gone. It is not recommended to copy from the computer to the memory card because the computer writes the files in a different format.
