Yep. I totally agree with everything you said. I should have been explicit that I just meant the original window design.
There are bots on Google and elsewhere that can find similar images, and there are a few people who design for profit who do use them to find unlicensed duplicates.
I recently had a frustratingly humorous issue with this. I do lots of Print on Demand stuff, and uploaded a design to a site that has been successful for me on another site. The site has a bot that does this and they flagged my design as copyright infringement … When I pointed out that it was my design that the bot thought I was infringing upon, they refused to allow it unless I sent them a copy of a registration letter from the Copyright Office. Common sense be damned. I reminded them that registration is only really useful to me if I expect to be suing someone else for infringement, and therefore not worth the $35+ fee and 8 month wait in exchange for the possible joy of earning less than $1 for selling a mug. I told them I was going to make a tiny (really, almost undetectably tiny) change in my design and re-upload; that way the bot wouldn’t flag it. They didn’t respond , but they didn’t flag the design either.
