What's format of JPG needed for it can be displayed on Penta

Hi
I really want to know how upload any JPG file to camera and it can be displayed on camera.
How I must prepare my JPG files for it will be displayed correctly on a camera (Pentax OptioWP)?
Thanks

Think of your camera as just another hard drive. Assuming you are using Windows, open up 'my computer', you'll see your camera listed as another drive. Go into the folder with your images and simply click and drag the image you want onto it.

It's not too simple. I can copy any files (images) to my camera, but I cannot see this images when I use camera without my PC.
My question is what secific format of JPEG must be to solve my problem.

Actually I think it's more than what format...

I know that if I move files (even the originals) back onto the card and put into my *ist-D it won't necessarily display them

Don't know whether the cameras look for a specific order or directory format, but in my experience not many cameras will correctly display images that have been placed back on the card by a PC.

I noticed that same problem with both canon and pentax cameras. I thought it'd be great to keep a sample portfolio on a spare card and carry a video cable for impromto slide shows...no dice..wouldn't work.

For canon I have original software wich convert any photos to necessary format.
When I copy photos back onto the Pentax it's OK. But file names must be correct.
When I edit photos from Pentax in MS Paint and save it is displayed in Pentax exactly. But when I edit photos in Photoshop it doesn't.
I try resave photos in Paint after editing in Photoshop it didn't work .

Devices like the Epson P2000 are designed more for the purpose than a camera is.

I think you're trying to do something that a DSLR will find uncomfortable to deal with. I would be wary of filling up the card with a directory structure that confuses the camera.

johnriley, it is offtopic

I think this is a general issue with most manufacturers. I'm thinking that the file format specification needs to be so precise that, after editing, then copying it back to the camera, it doesn't work.

Even sometimes just saving the file to a PC, and copying it back doesn't work. I have the same problem with my Fuji F810.

Don't forget that a cameras filing system is never going to be as clever or sophisticated as a PC for it to be able to determine the needs of many different file types ( I might regret saying that one day). The camera will have been told what it can display and if the file you are trying to show doesn't fit that criteria exactly, it will not display because the camera doesn't know how to handle the changed file.

This may be a question for the technical bods at Pentax to answer.

It could well be to do with the file system of the memory card, although nominally a FAT system the camera manufacturers always recommend that you format the cards in the camera, not on the PC, which suggests they may be doing something "extra". I also note that most of the undelete utilities require a special version to handle flash memory cards (but that may just be a marketing ploy!)

I formated my card on this camera. Even if I copy images to intenal camera flash memory (not card) then the problem exists too.

The bottom line is:
no one has found a camera (Pentax or otherwise) that will do this.

(Technically it is probably because the camera takes a simplistic view of the filesystem and cannot read a directory generated by a PC.)

As John said (and it wasn't off topic) - if you want to display images while on the move, then a P2000, or similar storage device with colour LCD display is the way to go. Personally I edit my images and keep a gallery on my PocketPC for showing (using PDAmill Viewer).
