digiKam from trunk (KDE4) : libkipi now provide a virtual method + a signal from Kipi::Interface to handle thumbs from kipi host.

Note than if Kipi host do not re-implement the virtual method, the default KDE Thumbs KIO slave will be used instead...

With this commits, digiKam give an acess to kipi-plugins to handle internal thumbnails cache used to render image.

The first plugin wich will use this mechanism is SendImages.

Valerio, you waiting this feature since a long time to use it in SLideShow plugin. It's time to port your plugin to KDE4 (:=)))

Angelo, patch for likipi can be ported to KDE3 (look my commit #735775). It's not very complex to do, but of course binary compatibilty will be broken.

Feel free to decide to port the code if you want this feature in KDE3 (:=)))
