Can photos be labeled either with numbers or, even better, legends?
Since you can include three photos per step, it would be great if they were at least numbered so that they could be referred to in the text specifically. It would be even better if the photos could have descriptions below them -- like figure legends -- so that each part could be described in detail seperate from the instruction text.
We won't be adding extra descriptions per image, but to refer to a specific image, our users usually write "as shown in the first image" or something similar.
We do, however, have plans to improve our image markers. In the future, you'll be able to add arrows pointing at specific parts of an image. You'll be able to change the size and colors of these arrows to match the colors of the bullets and other markup that you can use.
