I was just experimenting with the PC.......... My tablet is defunct !
I think the initial problem was that the picture is not in an suitable format on Google or maybe Google dont allow linking. So I copied the image onto my "clipboard" pasted it into Paint and saved it as a jpeg, Then uploaded it as an attachment in the usual way.
I dont know how you would do it on an Android... I'm not even sure I can remember how I would have done it on the Windows tablet !
One way that usually works is to do just what you have done and some sad forumite, with nothing better to do, will post it for you.
Thanks Vic. Reason I'm asking is that I need advice on refurbishing my dinghy and think I'll get a better response with pictures rather than links which some won't be bothered to open.
