How can I find a specific Sim on Gallery using an image?

Does anyone know how I can find a specific Sim from the Gallery using just a picture? I have one image of her, and she might have been a popular upload. Any tips or tools I could use?

A while ago, I downloaded a Sim from the Gallery and created a story for her, but I forgot to save her to my library. I haven't been able to find her again, and I can't replicate her facial features. I did manage to recreate her outfits and style, and I even ran an image search, I found one single picture of her, but no clue about her name to look her up on the Gallery.

I'm not sure if the creator removed her, but I'd really like to have her back with her original face. Here's the image I found of her, in case anyone has seen her before.
