However I keep going back to the photos as I suspect that I know the woman!
When you say that you think you know her do you mean as a WG under a different name previously, or that you think you know who she is in civvy life? If the former then perhaps that additional information would help others respond to your inquiry, if the latter are you sure you want to go there?
Apart from this you've already highlighted the relevant factors that would deter me.
