Why was Mary Surratt not photographed after her arrest?

I agree with Barry and John's assessment; plus Mary being female may have been another reason. Women simply were not usually put in the public eye. All during the trial and even on the gallows, Mary shielded her face from public view. The drawings of her after the fact; i.e. the cover of Barclay and Company's trial transcript which contains her "supposed image" was published more or less shortly after her demise. Her likeness did not appear in any of the illustrated weeklies other her than her appearance as a tiny non descript figure in the prisoners dock.

Her likeness did appear as she supposedly "looked" while in the death cell in Leslie's and in the rather racy National Police Gazette, but again, seemingly after her demise.
