[Plugin: NextGEN Monoslideshow] Preset tuning per image

I’m trying to have different KenBurns effects for certain images, so I defined my own preset.xml file. But I can’t find the proper place for <image></image> definitions. I think they belong in the <content></content> section, but when I put an <image> tag in there, I get a text error message (I think it’s a 1085 error).

It also isn’t apparent what URL should be used as the source=”” field. The entire URL, only the filename, the gallery/filename…?
