Granite and distant snowy peaks

Leon offered me a solution, to copy my existing photos on my external hard drive across from my old computer to the new on a pen drive. It works.

Probably too painful for the poor souls involved,Colin!

All of what you say rings a bell at one time or other, Herb! whether personally or third hand.
Thanks to Leon's suggestion, I now copy a few photos at a time on a pen drive. I can still upload new photos to my old computer and edit them in Picasa. I can also migrate a few of those at a time too for uploading to my new laptop. The problem will come when I lose picasa on my old laptop. Google (yes that lot of gangsters again!) have stopped updating and servicing Picasa so I can't add it to my new computer which is Windows 10 (so there are also many surprising things I can no longer do, such as use Skype as the audio browsers are totally incompatible with certain apps, such as Skype, owned by Microsoft).
Google and Microsoft ... Words fail me!

well observed, I’ll think of a good new Group one day :-)
