>>4136878>>4137072It's just a guideline and a product of my own habit of putting the author's name and original image file source in the filename of my images if I had them at the time I saved the image. I think it's useful from an archival perspective, but it's not a rule of any kind. Yes, reverse image searches are very useful; if you think it's unnecessary, I will remove the note about sources from future thread OPs.
