The application fetches the images of famous personalities on runtime via Internet. I have used the image URLs from MediaWiki Commons which is available for public use, but when the application was rejected I emailed Google about the issue and they replied with this.
Your app contains images of well known entities (Bill Gates, Steve Jobs, Muhammed Ali, Bruce Lee, etc.) that are considered copyrighted.
There are other applications on PlayStore which are using photos of these well known entities.
The image I used for Steve Jobs:- Steve Jobs: Commons WikiMedia
I would like some suggestions from people who are familiar with this kind of legal issue. I would appreciate your help.
