Using Pandas `DataFrame` as Data with Skorch

I want to use Skorch as a simple wrapper of my model.
My data is a set of 80x80 RGB images.
Each image as a row in a Pandas data frame.

I want o build a process to use the data frame yet I need to have a pre processing step which rearrange the row data into a batch.

How can I do that in Skorch?
