Funny that it also happened to my G7 just a few days ago. After over
4000 shots and never missed one. Then, suddenly this "unidentified
image" message came up when viewing the photos. Sometimes, the shot
came up (small size), but then disappear. Sometimes, instead of
"unidentified image", it comes with a "question mark" symbol.
I also noticed that my SD card is being "depleted" slowly. After
cycles of cut and paste into the computer, the number of left over
photos to shoot decreasing. But this is perhaps a different problem.
Going back to the "unidentified image", I found the images are still
available ( 3 MB per photo), but I could not open in any photo viewer
software, I am trying to get specialist to try to open the file (if it
si possible).
About the unidentified image, I replace my G7 with a completely NEW SD
card, and so far it looks OK (but have not tried it many times, just a
few). I am assuming that the SD card that is broken, not the camera
(Crossing my finger :)). Try if you can get a brand new SD card and if
it is working.
I hope mine is solved, although I am still not 100% until I started to
use it again. Next time I may need to bring 2 cameras, just in case
the G7 is busted.
Yes, I also noticed when I view some of the saved pictures, there are
block of the photo areas which are mixed up with other shots. So,
Perhaps the formatting of the photo is not complete, or mixed between
photos ----> don't know if this is the camera;s fault... or the SD
card. I hope it is the card and nothing to do with the camera. Perhaps
contacts with the SD terminals (worn out after SD card is inserted in
and out many times. Unfortunately, I never download photos using a
cable connection. It is just too cumbersome. It is faster just to pull
out the card and insert into my computer. Perhaps this may be the root
of the problem. Connections or contact are getting loose?
I like to hear from others who experience the same problem.
I wonder whether it is time to trade in with the new G10. They will
pay me for $200 for a new G10 and pay the difference (another $250).
Mine was over 1 year old and so far, never have any problems.
On a different topic, I saw some photos taken in Lumix LX3 and they
are just perfect. I saw that the quality of the photo is better than
Canon DSLR 50D! ( Quality comparison - LX3 , Lumix G1 and Canon 50D -
in that order) I also saw someone taking panoramic photo at night and
it is spectacular, sharps and no grains. Should I start thinking of
Lumix LX3? DPreview just came out with their review of LX3. It has
9/10 for optics. Perhaps it is in the lens!. But I was surprised on
how excellent the photos taken by LX3. I wonder if others experience
the same thing with their new LX3.

With C1 program setting I have programed the camera to take 3 pictures.
(normal, under- and overexposure). Sometimes, mostly from picture no
257 in the used SD card, I get the information "Unidentified image"
when trying to look at pictures on the display of the camera. Viewing
the pictures on a PC some areas are distorted or with areas blank.
It seems to me as the camera has problems in writing information to
the SD card in certain memory areas. I have tried reformating,
different SD card manufacturers etc. with the same result.
Does anyone else experience the same problem?
