You can switch on Admin Mode by clicking on the Switch On Admin Mode link in the Admin Index. This allows you to view all of the administration menu items when viewing a gallery. Normally the Edit captions/Delete Photos/Move Photos/Mail Photos options are not visible when viewing a gallery because they are unavailable to most users of the site. Switching on Admin Mode makes them visible.
In order to switch on Admin Mode, your browser must be configured to accept cookies. This is the default setting for most browsers. All the PixWire system does is store the setting “admin:yes” in your browser's configuration so that it can be used on subsequent pages. It is removed when the browser is exited.
