Viewing photos

every time I click on a small photo to enlarge it I get a message that I do not permission to access this page.

How do I get the permission?

It probably means that the feature to enlarge photos is not enabled

Chrissy, where might I find the photo enlargement feature?
Thanks.

As far as I know there is no photo enlargement feature here.

Thank you: I thought I was the only one having to peer at little photos of pens for sale.
