Irfan View
Irfan Wiev have been my companion since my earliest connection to the web.
It's actual less than ten days since I told my daughter about it for simple picture handling as her Open Office couldn't do the simple task of rotating pictures and scale them down to only neccesary size to able a document with several pictures to be E-mailed:-o
Sadly it's not available for the Ipad on wich the majority of my IT-work is done these days, but at least the original picture program have the most common features.
