Extended Media Forwards

TL;DR: an exteraGram plugin that adds a Forward button to photos and videos opened from telegra.ph articles and rich messages.

Description

Media inside an Instant View article can't be forwarded, and media inside a rich message can only be forwarded together with the whole message. Extended Media Forwards adds a Forward action to the media viewer for both: it downloads the photo or video and sends it again from your account, with a link back to its source when there is one.

Features

• Forward from telegra.ph. Works on media opened from telegra.ph and graph.org pages, single items and carousels alike.
• Forward from rich messages. Single media and carousels inside rich (article) messages (on by default, can be turned off).
• Any Instant View article. Optional switch to allow the button on every Instant View page, not only telegra.ph (off by default).
• The usual share sheet. Pick chats in the app's own "Forward to" sheet, including a topic in forums, and add a comment.
• Source link. The sent media carries a link back to the page or message it came from.
