With the help of Torstein and from reading this forum, I've just adapted Highslide for use in an iPhone (or Android, BlackBerry, etc.) web app... you can have a look at what I've done...
Note: This web app was designed for use on a smartphone or other portable devices, so it might not work correctly in your desktop browser (it works in Safari and Chrome, also Firefox, but it won't work in IE)
In Safari on your iPhone, go to http://www.passageweather.com/mobi
(It works best when saved to your Home Screen, as it eliminates the URL/toolbar and status bars)
In the Android browser, go to http://www.passageweather.com/mobi
BlackBerry and other smartphones:
Go to http://www.passageweather.com/mini
In the individual Forecasts pages, press a button (Wind, Pressure, etc.) and you can view the individual images as a slideshow or step through them... If you change the orientation of the phone the control bar changes position to better view the image... If you're using a desktop browser, just resize the browser to see it change...
Have a look and maybe it can help you... good luck... and thanks Hilde and Torstein for your help and hard work...
