This plugin may cause catastrophic failure of your website, especially where images and templates are concerned. Contacting the company themselves has revealed they are fully aware of significant incompatibility issues with WordPress, other established main stream plugins and several common and widely used Themes. It has been recommended to the company and to WordPress that this plugin be withdrawn immediately until the developer has corrected these issues.
