Duh! I have that but keep forgetting to mention it. Good show léonie.

You're welcome.🙂

Once you installed the plug-in, it will appear in /Library/Application Support/iPhoto/Plugins/BorderFXExporter.iPhotoExporter/

To use it, select your photo in iPhoto and use "File > Export > Version".

You should see "BorderFX" as a tab in the Export panel. Click it.

Then the BorderFX dialog will appear. Experiment a bit.

Once finished, click "export".
