Thanks, Geoff,
Downloaded the file number you gave me, but I've got an update for the 20D. Is that the one I need or am I missing something?
Don't want to blow things completely.

And for all you others that tried to help me with monitor problem, DOH!! I had done something remarkably stupid,

Dialled in 3 stops under and didn't notice. Should have gone to Specsavers!!

Good Morning, Stefan & Snappy
As far as I can see on the Pentax Website there are no firmware updates for the 200d and I did format the cards in camera.
Can't understand what went wrong. Blaming the cards was perhaps a last resort but, apart from using a maximum of 4gb previously, I did nothing differently.
The images are on the cards it's just I can't review them. Mind you, I spent years doing the same with film,so just like old times.

Yesterday I loaded my K200d with a brand new 8gbLexar SDHC card, formatted the card in camera and took a series of 123 images.All shot in AV mode. I tried to review the images on the screen and got an error message "Camera cannot display this image"
Supposing a faulty card I replaced it with a second new card and after a further 43 images got the same error message.
I returned to an older card, which recorded and reviewed O.K.
Since this happened, whenever I review the images they look extremely dark although the downloaded images are fine,including those from the Lexar cards. Images shot in manual mode do review on camera fine,i.e.they look correctly exposed
Is an 8gb card too big or have I done something remarkably stupid?

Many thanks. Would never have thought of using e-bay. Maybe now I can get my cameras back.

My daughter has been given an Optio E65 without a battery. Does anyone know which DLi battery fits. Tried e-mailing Pentax direct almost two weeks ago and still waiting for reply.

Thanks, John. Elements will certainly ease my bank balance.I'll run my trial of CS and then possibly take your recommendation. As I said, it's all fairly new to me and I'm feared I'm too long in the tooth to change my spots.
Regards, Dave.

Thanks for all the help.Decided, with the help of TTK, to go for CS3, add the Plug-ins and go from there. Will post to let you all know how I'm doing. Thanks again.
Dave.

Sorry, guys. I'm using Photoshop 7, Windows XP, card reader and SDHCcards. Can load JPEGs without any problem. I'm told I can use Picasa to download PEF files but the real problem is that I don't know the correct action to take once I get them into the computer to convert them to Tiff or Jpeg. Still just playing at digital.
