Public Domain Finder Review: This is a new software that searches the public domain images for you on 42 different websites. By entering in their desired niche and clicking a button, your customers will be able to search on 42 sources and get the results delivered in a document. Imagine the time they can save with this app. Searching on each one of the 42 image sites could take around 3 and a half hours. With our app, it’s just 10 seconds. And they can edit the document, use it themselves or resell it to a third party.
