ExpressView Image Browser Plug-In

The main advantages of using the plug-in are:

All map images can be zoomed and panned without a plug-in, but enhanced viewing options (now including a resizable image-viewing window, easier panning, and enhanced zooming with a zoom-level indicator) are available through the ExpressView browser plugin, which replaced the earlier MrSIDBrowser plugin in 2003.

The plug-in works under Microsoft Windows XP, 2003, Vista, or Windows 7, and with Mozilla Firefox, Google Chrome, or Internet Explorer 7 or later. For reasons outwith our control, from 2011 the plugin is no longer available for Apple Mac OS computers.

We recommend that you download this by clicking on any of our map thumbnail images, select the View with plug-in option, and follow the on-screen auto-download instructions. Alternatively, go to the download section of and download the 'ExpressView Browser Plug-in (MrSID) for Windows'. Run this so that it installs Express View, and check that it creates two .dll files in the "C:\Program Files\LizardTech\Express View\" directory.
