There are a number of ways to accomplish this, but the one I use is to make
the x and y axes invisible (gets rid of the ticks) and also make the spines
invisible (gets rid of the lines). I just throw these changes into a
utility function (`clear_frame` below) and put that in a module that's on
my python path so that it's easily reusable.
Hope that helps,

import numpy as np
import matplotlib.pyplot as plt
def clear_frame(ax=None):
if ax is None:
ax = plt.gca()
ax.xaxis.set_visible(False)
ax.yaxis.set_visible(False)
for spine in ax.spines.itervalues():
spine.set_visible(False)
img = np.random.random((100,100))
plt.imshow(img)
clear_frame()
plt.colorbar()
plt.show()
