I saw some key chain digital viewers that hold about 60 pictures. :eek:
So I am cheap 
and want to take my favorite pictures of the week and put them on a spare SD card (canon) or a XD card (fuji) using my card reader like a thumb drive. 
But … 
No matter what extension I use, ( jpg - bmp - tiff - raw ) the cameras won’t show them in playback. :mad:
Am I missing something or will it just not work? :smack:
The camera probably needs a very standardized file structure to be able to find the images. Try looking in the camera card output existing folder structure, e.g., DCIM\DC102, 103, 104, etc. (they all use different folder names, and the file handling options you choose in the camera’s settings also affect this) and see what happens if you take the existing folder structure and increment that folder arrangement by one and paste your favorites into it. Don’t open, edit, rotate, re-save, etc. the photos in any other applications prior to doing this, just select and move them as-is.
You can’t just put files on a camera and expect it to display them. They have to be in the right file structure and file naming format.
What everybody else said. Many cameras will not display photos once they’ve been manipulated in any fashion. I can transfer files from the card containing files from my Nikon D60, view them on the PC and transfer them back to the flash card, and view them on the camera. But if I’ve re sized, cropped, or manipulated the file in any way the camera will not recognize the image.
Rats… Thanks guys…
Well a lot of cameras will display any images in the format they can handle (typically YUV422 JPEGs) that are given correct DCF filesystem names. Try creating the following folder/file structure on the card:
DCIM/100XXXXX/PICT0001.JPG
if that doesn’t work, take a picture with the camera, it will be placed in the above styled folder structure (DCIM/NNNXXXXX/YZZZNNNN.JPG, where N is digits, X and Y are letters and Z’s could be digits or letters), then follow the same naming convention but using different numbers in NNNN – they typically don’t have to be sequential, just distinct.
Just to make sure it isn’t the obvious, is your camera default set to the internal memory and you’re looking in the wrong spot?
I just loaded 2 pictures from a 6 mb camera on my cell phone without any problems. I used the camera format of jpg. Is it possible you’re loading jpg files with the jpeg file extension? If that’s the case just take out the “e”.
