Plot two images side by side with skimage
See skimage.feature.plot_matches, pass empty list of keypoints and matches if you only want to plot the images without points.
Looking up at different feature matching tutorials I've noticed that it's tipical to illustrate how the matching works by plotting side by side the same image in two different version (one normal and the other one rotated or distorted). I want to work on feature matching by using two distinct images (same scene shot from slightly different angles). How do I plot them together side by side? 
I'm willing to use skimage on python 2.7
