Absolutely! I never figured this out till later - I actually went the 
hard way around and added the apps working directory + "/plugins" to the 
qApp's library path list like so:

QString pluginPath = QString("%1/plugins").arg(QDir::currentPath());
qApp->addLibraryPath(pluginPath);

Silly me - I never thought to just paste the 'plugins/imageformats' into 
the apps working directory...crikey!

Ahh well, live and learn.
