Signal should be present in the iOS Share Sheet so that it's easy to share things in Signal from other apps.
In this image you can see typical messaging apps like Facebook Messenger and iOS Messages listed in the iOS share sheet when I try to share a Tweet, or any other kind of content:

Singal should appear in that list, although currently it isn't possible to add it.

Not sure if #650 or this issue should be closed, but they seem to overlap in scope. An all-encompassing share extension could work for images, links, & other stuff. Currently exploring Evernote's extension.
