Why do some of my JPEGS not read on my DVD player?

[dalejoey]

I am helping my dad out here as it is really his problem. For some reason, when a disk is made (CD-r / CDrw) with JPEGS on, taken from his cannon digital SLR, some, but not all, of the pictures do not read when we have tried to view them on his Sony DVD player. This only appears to be from certain cameras as all the pictures I have viewed from my Sony cybershot have worked and from another camera have worker also.

The JPEGS have all been added in the same way - i.e. directly through the PC by putting the memory card in the PC, putting a CDr in the drive, openning both folders to view the files, selecting the pictures we want on the disk, dragging and dropping then writing the pictures to the disk. Not by using any software either.

The pictures appear to be fine in the camera and on the PC but just some of them it doesn't like. And they aren't too big files either - the limit is 4MB and the pics are around 2.7.

The DVD player is 2 years old and a pretty good spec so shouldn't have any trouble reading the pics.

thanks - if anyone knows!

Too high resolution?

cheers....

I have recently found out that the files that the DVD player cannot read are above the 4MB limit that it states in the DVD player's manual... so...I'm now considering purchasing some slide show software (can't seem to find any free downloads for that) but I'm not sure if it still won't play the pictures above 4MB. Does anyone know if the slide show software condenses the files down?

4Mb is awfully large for a picture. Can you shrink it down using an art package such as MS Paint or Photoshop at all?

[dalejoey]

Yes I know 4MB is rather large for a JPEG file, which is why I missed it at first. I wonder if it is to do with the fact the camera is an 'SLR'? It's not a huge mega pixel camera (6.3MPX) which is why I was supprised when some of the pictures were 4/5 MB! I have an 8.1MPX point and shoot and the pics are never any bigger than 3.4MB.....? Any suggestions?

Thanks

I personally would open them up in MS Paint and "stretch" them down to say 50% or even 25% depending on how large they are. This will reduce them from 4Mb+ to maybe even 50-100Kb.

You may lose some quality but it's a case of trail and error to get a compromise between usability and fileseize.

Thanks very much - I will give that a go.
