Replacing with original colormap in Matt's snippet doesnt look any
different.

[img x]= imread('http://www-ece.rice.edu/~wakin/images/lena512.bmp','bmp');
colormap(x)
imagesc(img,[0 255])
set([gcf,gca],'units','pix','pos',[0 0 512 512])

Can you explain what exactly doesnt look 100% like original (btw what is
the 'original' ?)

Ok you people are right. With imagesc and colormap the image looks good. The problem happens when I save the figure as a bmp file (that's why I trough the problem was when opening the original image)
