Move site images from imgbb.com

[DavidAJohn]

I'm regularly having issues with imgbb.com returning "503 Service Unavailable" messages with some or all of the site's images.

If it had been a one-off I might have accepted it, but this is happening far too often now.

It's time to move them all - either to another free provider like Cloudinary, or perhaps just to Azure.

Cloudinary add a suffix to each file, which makes things a little awkward because I'd still have to specify the exact URL of each image when referencing it in an image tag.

I'd like to eventually move to a situation where just the filename is specified and a root URL can be prefixed dynamically.

Azure it is then...

Any hard-coded references to imgbb.com in the code have now been dealt with, but there are still references in the Products database that would need to be updated manually.

These references come from the 'products.json' seed data file.

I've created a separate issue for making the image paths more dynamic here: #30.
