Problems viewing photos

Probably the images are not lost and do not need to be "recovered". Sounds like something happened to interfere with the operation of the program that knows how to display those images. Perhaps some other software was installed that messed up the program in question, or messed up the "file associations" (the thing that tells the computer that a particular program is used to work with a particular kind of file). I would try reinstalling whatever software program you had been using to view the images in question, i.e. before this problem occurred, when you used to open one of the photos, what program was it that appeared with the photo? That's the program I would reinstall.

There are four possible reasons that this could happen, so you need to do some tests to diagnose which one it is.

1. It could be that you shot some photos in "RAW" and the photo viewer is not capable of decoding raw images. (You should have a digtal developing software such as LightRoom for this, or installing the right Canon software might include the decoder that allows other programs to access it.) To test for this, check the full name of the files; if you can read all the .JPG files, but none of the .CR2 files, this is your problem.

2. It could be that your card is corrupting the data. To check for this, try a different card. (Any card will work for photos.)

3. Failing the other two, either the camera is producing corrupted data, or your image viewer is not capable of reading them. To discern which, try a different image viewer. If you don't want to install one, upload it to a photo sharing site, or just view it in your browser (you can drag and drop).

Its memory card problem.Every time format card after transfer at system and less try to delete photo in camera.Some time it give trouble to read memory card

I can't tell you exactly why all your photos became unavailable on your camera, but I do know that many digital cameras as well as handheld media devices (zunes, sansas etc) are very fussy when it come to the images stored on them. They write index files describing what is stored on them, and yes, if your alter any files using a computer after they were imported and indexed, they will disappear from view on the device. I am surprised that all your photos no longer show up, not just the ones whose orientation was altered.

I recommend moving your photos to your laptop and using your camera to reformat your memory card. I am unaware of any way to coax them into being viewed on your camera once they have been shunned.

If you format, you will lose everything...format means erase and optimize. Take your card to a store like Walmart that has a Kodak picture maker machine. It will usually read all the pics on a card and you can make a cd of them on the machine.

Thats a good question. Can you view the same picture on your computer? have you edited the photos you are trying to view (even rotated them on the PC), or re-named them. If you have renamed them, you will need to change the name back to the same format as they were when taken EG: NI7000001 (similar number is OK, but must have the same amount of characters in filename) ..., connect computer and browse to folder where photos are, see if the ones you are trying to view are viewable on pc, and check their names. also see if the size of the ones you are trying to view are smaller or larger size, as they may be corrupt. I would copy them all off the camera and then format the card in the camera. A lot of problems occur when the card is not formatted for long periods of time.

It may be of your new SD card. Try with another SD card. It may not show you File contains No Image Data. -Lalith

Make sure the image file is in JPG format, or the player won't be able to read it.

For users running Windows XP with Service Pack 1 and above:
With your device connected to your computer, click on My Computer and then click on the icon for your device. If you see a folder labeled DATA, you must copy the photo files you want to view directly into this folder. Folders containing photos cannot be copied to the DATA folder. Photo files must be copied directly to the DATA folder using no other folder.
If you do not see a folder labeled DATA, then copy the photo files you want to view directly to the device. Folders containing photos cannot be copied to the DATA folder.
