I have been collecting photographs digitally for almost two decades. I would download whatever I found interesting and keep it organized as much as possible. However, with over 300,000 photographs on my hard drive now, it is far from perfect. Currently, if I want to learn more about a particular photograph, I upload it to Google Image search to find out more. I am now looking for an app that can do this automatically. Does anyone know if something like this exists? Essentially, I am seeking an app that can perform reverse image searches on the entire library or a selected folder locally?
