Ahem, shouldn't the user-developed plug-in with extension .usr be listed in the "Plugins user" section?

Hi Arty

I would love to install your plugin on mac. Any chance you have a mac friendly zip version?

Thanks

I'm running XnViewMP, but the plugin doesn't appear to generate thumbnails for the two "lena_*" images in the \test\ subfolder. Am I doing something wrong?

Thanks!!

Hi.
This is because this plugin is developed only for XnView not for XnViewMP version.
