Simple (without resizing):

GET http://localhost:3000/images/{FILE_ID}.{EXTENSION}

http://localhost:3000/images/3SSU9PrP8CthgEWobCfKKetBL8q8.png

With resizing:

GET http://localhost:3000/images/{WIDTH}x{HEIGHT}/{FILE_ID}.{EXTENSION}

http://localhost:3000/images/100x100/3SSU9PrP8CthgEWobCfKKetBL8q8.png

Proxy:

Image will be downloaded first time and cached

Simple (without resizing):

GET http://localhost:3000/proxy/{IMAGE_URL}

http://localhost:3000/proxy/https://i.gifer.com/1HOf.gif

With resizing:

GET http://localhost:3000/proxy/{WIDTH}x{HEIGHT}/{IMAGE_URL}

http://localhost:3000/proxy/859x356/https://i.gifer.com/1HOf.gif

You can proxy images that have been uploaded to this hosting too:

Link http://localhost:3000/proxy/100x100/http://localhost:3000/images/3SSU9PrP8CthgEWobCfKKetBL8q8.png will have same effect as: http://localhost:3000/images/100x100/3SSU9PrP8CthgEWobCfKKetBL8q8.png

But it good idea to reformat that links in short form, otherwise we can take urls like:

http://localhost:3000/proxy/100x100/http://localhost:3000/proxy/320x320/http://localhost:3000/proxy/http://localhost:3000/images/3SSU9PrP8CthgEWobCfKKetBL8q8.png
