Uploading Images to my camera storage media

[Silvernail]

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


SilverNail:~# ls /mnt/sdc1/dcim/100canon
ballareina.jpg goldtree.jpg greentree.jpg gulls.jpg washerwoman.jpg beggingman.jpg greenman.jpg greenwoman.jpg suntree.jpg


And can verify that they are there using 'gimp' to view them directly from the camera.


SilverNail:~# gimp /mnt/sdc1/dcim/100canon/*jpg


However I can not view them with the display function of the camera. What is the difference between a jpeg created with 'gimp' 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/

I'm guessing that most cameras must write some metadata to the file that it reads when loading the picture and recognizes that it was taken with that camera. Once you modify an image that metadata must get erased and then the camera does not recognize that image as one of its own as it seems most cameras cannot display an image if it was modified or taken with a different camera. At least that's been my experience. I've tried to put a picture on my camera that was taken with a different camera and it would not display it.

OK,,,,,,,,,,thanks for sharing the information.

I guess if I want to show my art work to this chick she is going to have to get a laptop to view the flash drive.

Just invite her back to your place to view your etchings. :D
