Thanks lynn0012

if you don't mind, how do you use Google image in this case? I didn't know the name (what to search) etc.
I was using tin eye ( tineye.com ) but it only returns the exact / same images.
Out of topic, while using tineye, one thing led to another (you know how it is

) and I found this website:
gallery-dump.info
lots of galleries with "only" hundreds (like 300 - 500) views, so.. it might be a gold mine
