Bug in imread

Hi,

I've found a bug in imread which causes images in PNG and JPEG format to be flipped when using imshow. For example,

import matplotlib
matplotlib.use('Agg')
import matplotlib.pyplot as plt

fig = plt.figure()
ax = fig.add_subplot(1,2,1)
image = plt.imread('2mass_rgb.png')
ax.imshow(image, origin='upper', extent=[0.5,723.5,0.5,724.5])

ax = fig.add_subplot(1,2,2)
image = plt.imread('2mass_rgb.jpg')
ax.imshow(image, origin='upper', extent=[0.5,723.5,0.5,724.5])

fig.savefig('rgb.png')

The input and output files can be found at https://www.dropbox.com/s/96npxuglpkd7y1u

I have submitted a bug report at https://github.com/matplotlib/matplotlib/issues/101

Thanks for any help,

Cheers,
Tom
