This is a small little helper site that I wrote to generate one image with four images from cloudinary. It was getting tedious to use the url format to get this working.
I just this to generate preview and social media images for my blog civicopendata
Url for the above image:
https://res.cloudinary.com/demo/image/upload/c_fill,h_600,w_800/c_fill,h_600,w_800,x_800,l_nice_couple/c_fill,h_600,w_800,x_-400,y_600,l_nice_couple/c_fill,h_600,w_800,x_400,y_300,l_coffee_cup/coffee_cup
