If you wish to create a SimpleViewer gallery in a WordPress post you could either:
(1) Use the dedicated WP-SimpleViewer WordPress Plugin: http://simpleviewer.net/simpleviewer/su … pleviewer/
... or:
(2) Create a gallery using svBuilder-Pro (or any other method of your choice), upload the entire gallery folder (not just the contents) to your web server, and embed it in a WordPress post using one of the two methods of embedding described here: http://simpleviewer.net/simpleviewer/su … dding.html

A SimpleViewer-Pro gallery created with svManager can also be embedded into a WordPress post using one of the two methods of embedding described here: http://simpleviewer.net/simpleviewer/su … dding.html
Please note that if using the <iframe> method, the gallery's index page will be named 'index.php' rather than 'index.html'.
