I’m using a discourse powered site called blender artists, and they have an exceptionally low limit of 5mb for media added to posts. Here’s the link to the post I’m having problems with: Power Paste Addon 
- Coding / Released Scripts and Themes - Blender Artists Community
To add 30mb gifs to my post, I’ve stored them on an external server, and added the link. They display fine in the edit post preview window, but as soon as I submit, the website tries to download them, and then blocks them for being >5mb.
I’ve spoke to the guy that runs the website, to see if there’s a tag I can add in the edit page that tells the site to use them from their external location rather than trying to download them to the websites server. He’s unsure, so has directed me here.
Post editor:
Live Post looks like this:
Paste into pre-configured particle systems to generate landscapes in seconds:
https://assets…(image larger than 5 MB)](user has to click link to download the gif to their computer if they want to see it!
So maybe I can wrap the gif link in something to tell the server to use them from their external source?
