Add-on Convert hot-linked images to attachments in XFRM

[Daveo16]

I'm looking for an addon that converts any hot-linked images in XFRM to attachments.

I did contact AndyB, who wrote a similar addon for xF 1.5, but he is not interested in updating the addon for xF 2.3.

Therefore, I'm looking for someone to make such an addon for xF 2.3.
