I had to take down the gallery before of high CPU activity on the server it is running on.
Update – I traced the issue to over zealous robots and other spiders, from Google to Majestic 12. It will take a while before they all receive new instructions to stay away from my images via the usual ‘robots’txt’ file. Until then, the gallery will remain protected by password.
You can still view part of the content of the gallery using the links to offsite images from the gallery main page.
