They don't wear out as such but SD cards can only be written to and from a certain number of times.

Are you saying when you try to view the image it says it's not compatible and then gets wiped?

Thank you alan for your prompt reply.

What happens is that I view the photoe on the camera & any good ones I print

on the printer, I then load them onto the computer & then erase them on the camera.

On some subsequent use when trying to view it a blank screen appears with a large question mark & the IPEG message.

I think from your previous message this is the problem.
