...
I use the search on a regular basis when I get curious. I recently bought an older oddball electronic device for $.25 at a resale shop, but didn't know what it was and wanted some info, but had no "starting point" to search... no label, model number etc. I scanned the item, and dragged the scan to Google Search, and the pic came up... w/identification and model number from which I was able to download the manual. (It was a remote sensor to tell if the garage door was open or closed, from inside the house.)
Give Google search a try. Even older pictures of persons will come up. I've found names for high school pictures taken 60 years ago... people who were never famous...
