verbose 0 (138: primitive.py, options) WARNING: Ignoring option 'title'=Lena image

and indeed there is no title. In Sage 5.3 we have the following picture, as you point out.

But compare

sage: matrix_plot(data,axes_labels=piclabels, title='Lena image',origin='lower')

So I think that this will be pretty easy to fix by moving the title like we do for regular plots. I've opened Trac 13625 for this.
