+ * @short Structure describing a picture on disk
+ *
+ * @note We use the *nix epoch (1970-01-01) as a time base because it is a valid date.
+ * That way we do not depend on a behaviour of the current QDateTime that might change in future versions of Qt
+ * and we are also nice to non-Qt programs wanting to read KOffice's files.
+ *
+ * @note This behaviour is also needed for re-saving KWord files having \<FORMAT id="2"\>. When saving again,
+ * these files get a \<KEY\> element as child of \<PIXMAPS\> but not one as child of \<FORMAT\> and \<IMAGE\>.
+ * Therefore we need to be careful that the key remains compatible to default values 
+ * (another good reason for the *NIX epoch)
+ *
+ * @note In case of a remote path, the "original path" is the name of the temporary file that was
+ *  used to download the file.
