Image uploading is a common feature in many web/mobile applications.

We are going to be using the Image Upload feature extensively in Time
to allow people to upload a photo showing evidence of their completed activity.
(if you cannot visualise the use-case of this, please comment in: dwyl/app#215)

Additionally there are several classes of applications where image uploading is relevant:

• Dedicated Photo Sharing App (the obvious one)
• Messaging/Chat (where "a picture is worth a thousand words") Look no further than SnapChat!
• Personal/Company Finance & Accounting (Uploading Receipts)

By building a clearly-explained Image Upload example/tutorial with re-useable code,
we can help others get creative and spawn new Apps/Projects in the community.

Todo

• Create an start-to-finish Image Upload Example
• Deploy it to Heroku
• Make the code generic and modular so that anyone can use it in their project.

Questions we need to ask/answer:

• How do we secure our /upload endpoint to avoid people using it maliciously to upload undesirable images.
  • Can we restrict the Origin of the upload?
    • Can the Origin be spoofed by a command-line script?

I'm not saying that we are going to create an "image upload" product,
But the ability to upload files/images is a "standalone" feature that people pay for!
e.g: https://apps.shopify.com/uploadery
This is a feature that has real value to end-users so if we build something great
not only will the people using the @dwyl app find it useful,
the wider community will use it and help us to improve it!
