Canon G7 - I can't copy images back to the camera

Just bought a Canon G7. One problem. Once I move images out of the
camera to my PC, I can't copy them back to my camera. What I do is
open Windows Explorer. Copy the pictures that I want to copy. Go to
the drive named Canon G7. Right click, but 'paste' is greyed out. So
I can't paste.

I want to do this so I can show the pictures on TV for my family to
see. Does anyone know anything about this? Can it be done? I don't
have a memory card reader, so using the card outside of the camera
isn't possible for me.

You may also have noted that using Windows Explorer, you can't
format the memory card or do a checkdisk. Those are greyed as well.

The reason is that Canon cameras don't let you access the memory card
as if it were a drive. It uses a protocol or a set of commands to
communicate between the camera and the computer.

Windows has incorporated a routine to send commands to cameras
like Canon using Picture Transfer Protocol (PTP). They fetch the
images this way and then display them in Microsoft Explorer.
This makes it appear that you are accessing the images directly
from the memory card, but you are not.

Windows does not have the proper commands built in to put images
back into the camera. For that you need to use the supplied Canon
software that came on the CD bundled with your camera. That means
installing the camera drivers and installing Zoombrowser.

Nicely explained. My little Soansa mp3 player works same way using
something called MTP. Both for the camera and the player, the directory
structure shown in windows explorer is not same as shown when using the
device not in windows. The easiest way to put pictures in camera is to
use a card reader to copy to the picture directory. Although canon
maintain a not too easy to follow algorithm for directory names, the
couple of time I've violated the rules (to fix file numbering), the
camera didn't seem to mind. I'm not sure what may ensue if you edit
pictures outside camera, but you won't hurt anything by experimenting.

Boy am I glad I use Linux!

You can put the images back into the camera provided you use a card reader.
I even did this with my wife's photos into my camera. However, her camera
was a smaller model. She has a point and shoot and I have a Rebel XT. In the
same manner, I could not transfer mine into her camera because the size of
my photos is much too large.

Some cameras will accept a memory card with computer saved JPG files. They
may or may not be able to properly read them.
Not having a card reader is less than ideal. Turns out that downloading
pictures from a camera is slower than using a decent card reader, and
naturally, uses up the camera battery. I occasionally use a PC based camera
control program, so I invested a few more additional dollars in a camera
power supply.

OK, after reading the responses, I have one, probably stupid question. Why
would you want to put an image back into the camera after downloading it in
the first place?

The funny thing is that Canon wants us to think this is progress when
every user thinks it is a bug or a stupid omission. Older cameras
supported reading and writing to the card from within OS X and Windows
so why does Canon and other manufacturers think this is an improvement?

I'm not the OP but I suspect that he's grabbing his best shots from
multiple shooting sessions and would like to put them back on the camera
so he can connect his camera to the TV to show his "slideshow". It's the
new version of our old Kodak Carousel shows. :)

Do visitors still fall asleep when seeing hundreds of family pictures as
they used to with slideshows? ;)

When they're done like that, I imagine they would. Done properly with an
appropriate soundtrack and even video clips, a slide show can be much more
interesting.
