Upload pictures directly from url

[Eknir]

Quite often, I share a picture with people. Ideally, I would like to share this picture via Swarm. The workflow to do this right now:

1. Find picture on the web
2. Download picture via browser UI
3. Upload picture to the gateway

I think we could simplify this flow to:

1. Find picture on web
2. Get URL from picture
3. Paste URL in the gateway (?) and upload it to Swarm

Last weekend, I wrote about this:

So, basically, I have this picture (https://www.bl.uk/learning/timeline/external/mappsalter-l.jpg) that I want to upload to Swarm. Right now, I need to download this (I do it via the browser UI, but could probably also do this via wget). It would be convenient if I can just add this picture to the gateway (or perhaps another Swarm product/utility?) and that then the gateway fetches it from web2 and ports it into Swarm.

I don't know whether this is a feature that should be gateway-specific, or whether it could be a small tool, that then can be integrated in the gateway (but also in other services perhaps).
