No need to apologise fourm member, I know you mean well.
I have addressed may of the points you brought up but I can't see any trailing 'C' after the closing </html> tags on I presume the home page or the about page.
Galleries will slow down once 'new' images arrive. That of course is all up to the photographer as is the actual choice of images. I am aware I have some responsibility for them, but I have decided to limit that to number of images rather than the actual images.
Thanks for the info.
