Phil
Thanks for trying the slideshow, glad it worked for you ok. It took me several evenings to compile it, will have more to add to it, and replace some of the smaller pictures in there, which were taken several years ago.
Regarding copyrighting the pictures, as each slide is only about 50kb, if they are copied they will never make a good hardcopy for printing to any decent size.
Putting a watermark on each picture, if the mark is somewhere around the edge it can always be cropped out, and if towards the centre it will spoil the picture for all to see. I do appreciate what you say Phil.
