Hey Joshua, π
I see how this can be something that can be useful for topics API projects for example. π
But I don't think this should be a part of together itself, besides it is already possible in a way. You can already embed images into your together posts on the web interface, and if you combine it with markdown you could create a working button!
See this topic about markdown:
