A link there will let you see a "video of an electron." You can judge for yourself whether to call it a photograph; but in the absence of more information than is given in the "press release" I would take it as a "very loose description" of what (if anything much) was done.
The investigators do claim to have been able to produce "attosecond laser pulses" (10-18 second) at high repetition rates, and recorded artifacts with a "camera."
