nctalk: Images are not embedded in message when send from other messengers

[mpietruschka]

Describe the bug
Matterbridge: I'm using the master branch.
Nextcloud: 27.1.8

When I post an image to whatsapp its not embedded into the nctalk message. Instead the message holds a link to the matterbridge mediaserver. Same behaviour when send from telegram.

When I post an image in nctalk, then its transfered to whatsapp nicely.

Sending images between telegram and whatsapp works great.

Text messages are bridged perfectly.

UPDATE
I tested v1.26.0 (from source) and sending images from telegram to nctalk. It doesn't work.

To Reproduce

Nothings special.

Expected behavior
Send embedded images/media from whatsapp/other messengers to nctalk, too.

Screenshots/debug logs

Environment (please complete the following information):

I'm running Matterbridge in Docker build with the served Dockerfile_whatsappmulti
