Thanks for your reply Old Toad.
I have merely dragged and dropped the photos to an SD card which previously had photos on it which were previously moved this way, see info on 16 GB SD Card attached.
Are you saying I should use the Export Function on Apple Photos?, this doesn't remove the photos from my iMac does it?
I have 5600 photos going back as far as 18 years, some of the images are very small and can't really see them on the 48" TV, so if i could see the photos in a directory list (like good old windows) I could delete the small ones from the list, also I could also see the size of the sum of the photos and better judge whether they will fit on the 16GB SD Card
I don't see the purpose of exporting them twice as it took an age exporting them directly to the SD card and it packed up after about 3,200 photos ?
I have one of those Kodak photo frames which is what I wanted to use ideally, you don't seem to be able to buy them any more but now if I try this SD Card with 3,200 it doesn't load the photos, the same SD card previously had 500+ photos on it and it worked OK, so I will probably ditch that idea and just use the TV via the USB connection, don't know what your thoughts are about all of that?
Thanks for your help so far, and would be grateful for any help with your expertise to sort this problem for me.

Rob
