Hello,
I have created a very basic web app (with as less HTML as possible and I hope to improve UI) that classifies Alligator vs Crocodile (Apparently they are more similar than I thought) with a total of 400 images. Please give it a try. I am also planning to train a model on more images. 
Thanks for trying.
EDIT: I have removed the link and moving my app to more stable solution like Azure Webapp or Heroku! Also I am working on the v2 (training on more data) Thanks everyone for your support.
EDIT2: Please find the updated app post here.
