ImageMonkey is a free, public open source image validation service. With all the great machine learning frameworks available it's pretty easy to train pre-trained Machine Learning models with your own image dataset. However, in order to do so you need a lot of images. And that's usually the point where it get's tricky. You either have to create the training images yourself or scrape them together from various datasources. ImageMonkey aims to solve this problem, by providing a platform where users can drop their photos, tag them with a label, and put them into public domain.
