/**
* @brief Represent a picture in Kopete context
*
* It kept a cache of a TQImage object, a base64 string and
* a path to a image file. It ensure that all source are synced.
* Interally, the image is stored in PNG format when possible.
* It can happen that the image path do not return a PNG file.
*
* You can only use an TQImage and a image path to create/update
* the picture.
* If the picture doesn't exist as a file, it generate a local
* copy into ~/.trinity/share/apps/kopete/metacontactpicturecache
*
* This class is implicitly shared, so don't use it as a pointer.
*
* How to use this class:
* @code
* Kopete::Picture picture;
* picture.setPicture(TQImage());
* picture.setPicture(TQString("/tmp/image.png"));
*
* TQString base64 = picture.base64();
* TQString path = picture.path();
* TQImage image = picture.image();
* @endcode
