a plugin-instance is bound to a specific image-size/format.
since [pix_freeframe] does not know which image-size you are going to 
process before you haven't send at least one image to the object, an 
instance of the plugin is only created after the first image appears.

parameter-changes are local to the plugin-instance, so you can only 
change the parameters, once you have an instance of the plugin which you 
don't have before the first image.
when you change the image-size during processing, a new instance of the 
plugin will be created (the old one is destroyed); this means, that you 
have to reset any parameters you have set before.
