Adding new images and removing an exisitng images index

[skt2211]

I'm new to using the NearPy package. I'm having set of images with their vectors of features that are already indexed. If i get a new image, Is there a function that allows me to add to specific bucket according to this image's similarity to other images already existing?

Also if i need to remove an index of a specific image that i deleted from my dataset, is there a function for that?

Thanks
