Sorry, I should have included that the filenames, all, either assigned by the camera/s, the software or by my renaming end in .jpg or .JPG and the processed image has been placed in the same folder on the sd card as the "out of camera" file that shows on the ipad. The folder chain is DCIM then 918ND800 then the image IAM_xxxx. The folder contains 3 images, 2 taken by the camera and one processed and renamed image. The 2 images taken by the camera show on the ipad, the processed and renamed image is not visible.
As for itunes, I neither want nor need software that tries to make me go to the apple shop every time it starts. If I want fruit, we have a good greengrocers handy.
Thanks Am, I don't feel inclined to ring them as I really don't think that they would like to hear what I think of a product that cannot work with other products without needing extra software that tries to sell you things or expensive proprietary connections.

Thanks for your help and thoughts Mathy, it has all been consigned to the too hard basket and just doesn't make sense to me. I will resort to other means of getting the images to them ----
