Google image search
Upload one or more images and search for a similar image in the google image search. Google returns a list of links and images which are close to the original image.
I tried this but mine failed too. Can you give me advice how we can use?
I like this feature. I tested it but received errors: on foto upload wappwolf states:

Dropbox failed: Upload failed: You must upload a file.
