In a post discussing the kind the of answer one would like: rigorous or heuristic, the need to attach a diagram with a solution was felt.

The other day, I was trying to tell the bijection between \(\mathbb{N}\) and \(\mathbb{Q}\) in a discussion and it would have been very easy had there been a diagram.

Again the new feature of "Contribute", (

*which I liked very much, for it is much easier than email, which doesn't even allow*\(\LaTeX\)), we see David always giving problems with diagrams, but again we cannot submit diagrams.

Please look into this.

Thanks.

TopNewestWe are looking into it. You are very right that a diagram would make many things, much easier, on many aspects of the site. For now, though it is not ideal, we encourage people to feel free to use services like imgur to host their pictures and to provide links in their comments, solutions, and problems for others to view them.

We will eventually have the ability to submit your own image or diagram, inline with your discourse, however it won't happen immediately.
