Ask HN: What API do you wish you had while building your product?
An API for handling image processing/uploading to S3:<p>Use 1: Send a high-res image in any format (like, say, tiff), the original, a web-optimal jpg at full resolution, and any sizes that might be needed in various contexts (thumbnail, inline display at any screen density) are put into the right place in my S3 bucket.<p>Use 2: Using ids or original file names, point the API to an image or array of images,  uploaded via Use 1, and give it a set of dimensions/conditions, and have it return links to the correct images for me.
