and so I've installed it at http://nuelr.org.uk/photos for general use. You will need to register individually to be able to upload images. This is a separate registration from your nuELR one.To assist new users I've also set up a couple of tutorials at http://nuelr.org.uk/tutorials
I'm sorry for the false start
but I'm sure that Gallery 2 will provide a stable platform of members who want to publish their images.
