"Loading" as a separate section

[joshmoore]

The dc-cac-image discussed during their first meeting the question of moving to imageio for data loading (#238 / #239). There was general support for the move on the basis that data loading and processing are sufficiently different concepts that it isn't a too great burden on learners.

Looking at the current outline of the lesson (and perhaps depending on what lessons might be introduced in the future), I'd like to open the discussion on if "Image loading" might not be an appropriate section in its own right where exactly the discussion that's been had in the issue, the PR, and now the CAC could be explained to the learner. ("There are multiple ways to load an image. The basis for this lesson is that any loader should return a numpy array. In future lessons, this can even be done for remote data." etc.)

Oh, yes! If not an episode, at least a section, indeed. Thank you for this great suggestion, @joshmoore.

👍

The basis for this lesson is that any loader should return a numpy array.

The next release of scikit-image will feature this note in its user guide:

(which comes from scikit-image/scikit-image#7159). We may want to include a similar note in the "Image loading" section.

On a side note, I just looked at the current section titles: They are not really consistent in form, but maybe the new section should be titled "Loading images" rather than "Image loading."
