Hi, I have only gotten as far as installing this plugin (not testing yet), but already it looks to me like your CSS was overriding my page's CSS, before I'd even put the plugin on the page.
Your CSS starts with .wpic_container html, then goes on to list things like body, div, span, applet, etc. when I think it should be .wpic_container body, .wpic_container div, .wpic_container span, .wpic_container applet, etc.
Just a heads up in case it was unintentional. Thanks for your plugin!
