Default Incompatible jpeg?

Hi
I have a Canon IXUS 70 Digital Camera and each time I remove the
memory card, put it in the PC, copy the pics, put the card back in the
camera to view the pics, a message comes up for a lot of them saying
'incompatible jpeg'

Would anyone know what is happening between taking the card out &
putting it back in the camera please?

How/what software do you use to copy the pics? It is likely that
thumbnails of the images are being created and being written back to the
card. I would hope/expect that the jpegs are not being modified, but
that is possible. More than likely the camera is complaining about
thumbnails created to view images.

I sounds like you might be changing the photos on your PC and saving
them back to the card.
Something as simple as rotating the image would do this.

Martin,

I wrote some software which can fix-up images for display back on the
camera. There is a trial version here:

To test, just drag/drop pix from card to HD...

Just a learning thing. I went through it also.

First never remove the card unless there is no other way. In this case
just download the pictures to your computer. Store them in an
organized location. Then after checking to make sure they are OK make
a CD.

Then erase the card in the camera and go back and take pictures
again.

The less times the card is removed from the camera the better off you
are. A pin repair in the camera body can be $150.00 or more and is not
a warranty item.

Different from my experience, Bob. In all my years of using CF cards, I
never damaged one or the camera. I /never/ downloaded from the camera
with a cable, I /always/ used a card reader.

With today's computers, many already have a slot to read the SD cards I
now use, so I have continued my practice of removing the cards from the
camera to read the images. With SD cards, there are no "pins" in the
camera, and I believe that the flat connections are rather less liable to
damage that the pin/socket combination of a CF card.

Like you, I do format the card in the camera before use, but my immediate
backup is now more likely to be a pair of portable HDs rather than CD/DVD.

Cheers,
David

Never remove the card?

I don't know anyone who does anything approaching even hobby levels of
photography who works with only one card. I change mine several times a
week at least and this is my eighth digital camera and I have never had
a need for a pin repair. However, should such a problem arise while
under warranty (and all my cameras are) it would most certainly be
covered by warranty. Using multiple cards in a camera is normal practice
and as such, is covered by the warranty.

By the way, while on the subject of warranty, I never fill in and return
the warranty forms, it limits my rights under law, it means that I am
agreeing to the warranty terms offered by the company rather than those
legislated by my local trading laws. I am still covered, under trade
practice law, even when I do not accept the offer to return the warranty
agreement.

Downloading large raw files via USB when compared to using a high-speed
card reader is enormously time wasting and inconvenient. I carry a
reasonably powerful laptop with a built-in card reader and Photoshop at
all times with my camera gear, and will often swap cards after just a
few shots in order to closely examine them while in situ to make sure I
have what I want before proceeding.

To each his own, but I find your advice to be a little strange.

My pictures are usually downloaded via a card reader on my laptop, and
then they are copied to TWO other computers for backup. Since my
'failure rate' with CDs has been around 75%, I wouldn't even consider
that for a backup medium!

Same here, but at that point it becomes almost a matter of religion,
like operating systems, text editors, Internet browsers...
