Question: How to use Seq2SeqSharp for image classification?

[WinInsider]

I am a bit a a lose, as to how to use Seq2SeqSharp for image classification... perhaps is not possible?

First step, as I understand for image classification is to extract features of the image (usually a float or a double array), for each set of image for given label (category). Then build model. Subsequently use new image against model, to obtain closest matching label/category.

Where should I look for an example.
