ImageGlass is totally free and open source. There is no ads in the app as well.
However, developing and maintaining it have been taking thousands of hours of my time and a large part of my sanity as well as my finance.
If you love this little app, it would go a great way to ensuring that I can afford to take the time to continue to develop it.
