Building a simple PicPaste replacement using Azure Web Apps and WebJobs

This post was supposed to be an introduction to Azure WebJobs, but it took a weird turn somewhere and became a guide to building a simple PicPaste replacement using just a wimple Azure Web App and a WebJob.

As such, it might not be a really useful app, but it does show how simple it is to build quite powerful things using Azure.

So, what is the goal? Well, the goal is to build a website that you can upload images to, and then get a simple Url to use when sharing the image. This is not complicated, but as I want to resize the image, and add a little overlay to it as well before giving the user the Url, I might run into performance issues if it becomes popular. So, instead I want the web app to upload the image to blob storage, and then have a WebJob process it in the background. Doing it like this, I can limit the number of images that are processed at the time, and use a queue to handle any peaks.
