The words right below the photo (the caption) were accurate.
The other words:
"Hajiyeh Esmaelvand was killed in such a manner in December 2004. She was accused of adultery. She is but one victim of this law of the Sharia."
was not part of the caption and was in regard to a different woman, who, as you pointed out, was not killed by stoning.
Thanks for clarifying. I actually didn't realize the named woman wasn't the one in the photo.
It appears that the image is actually from a movie:
