Website with photos named "gallery-number.jpg"

Welcome,
sorry for my weird question, but I have no idea where to find answer for it.
I've got a picture called "gallery-1234567.jpg" (this number is for example
of course) and I want to find where it was downloaded from. I suppose it is
from something like a photoblog, dating site, internet community or thing
like that. Maybe someone of you have noticed somewhere that kind of
filename - word "gallery", dash and a number. Big thanks
Dave

Complicated Google searches based on the filename

Reading any EXIF metadata that's in the image file itself.

Checking your browser(s) cache(s) to see if you can find an old copy,
with history.
