Re: Uploading Images to my camera storage media

I have uploaded some images to the storage media on my Canon camera.

ballareina.jpg goldtree.jpg greentree.jpg gulls.jpg
washerwoman.jpg beggingman.jpg greenman.jpg greenwoman.jpg
suntree.jpg
[/code]

And can verify that they are there using 'gimp' to view them directly
from the camera.
[code]
SilverNail:~# gimp /mnt/sdc1/dcim/100canon/*jpg
[/code]

However I can not view them with the display function of the camera.
What is the difference between a jpeg created with 'gime' and a jpeg
created by the camera. Or does the camera write a directory or some
other file that is needed to view the images.

Am I approaching this from the right direction?
Thanks for any help/

Hello Dave:

I wonder what would happen if you were to move an image, taken by the
camera, to your linux box:

# mv /mnt/sdc1/dcim/100canon/canonimage.jpg /root/Desktop/canonimage.jpg

Then, confirm that it's gone from your camera.

# ls -alF /mnt/sdc1/dcim/100canon

Then, reverse the move command:

# mv /root/Desktop/canonimage.jpg /mnt/sdc1/dcim/100canon/canonimage.jpg

If it can be /seen/ by your camera, maybe your camera's firmware edits
the file structure in a manner not followed by the Linux standard.

Also, does the "ls -al" command show any possible differences between
the camera's jpegs and those moved to the camera storage from another
source?

I'm out of my league here but, I wonder how close the Canon file system
spec follows the Linux file system spec?

Best wishes.
