Can tigramite be used for image data?

Hello! Can tigramite be used for image data? For example, a time series containing multiple variables (x1,x2,x3,x4), but each moment of these variables is a picture, equivalent to a four-dimensional data. Can we directly use tigramite to analyze the causal relationship between them? Still need to change the data processing code in tigramite

I also want to know about whether this algorithm can be applied to image data.
