Good info Scott. Here is my super-macro for Chat Pic posting. If you save this as a macro button, it provides an interface for posting pics so that the Player does not need to remember how to write the code, brackets and so on. This method will also display the caption text in chat instead of just hiding it. This has a default picture of a Roll20 symbol that you'll see in-chat if you didn't enter a new picture URL. So leave the code intact, you'll be replacing the image URL when you actually use the macro in-game. /me describes it so you can imagine this, ?{What is it a picture of? Write a concise caption:|Picture of } [Image](?{Image URL ending with JPG, GIF, or PNG|<a href="https://app.roll20.net/images/quantumroll2.png" rel="nofollow">https://app.roll20.net/images/quantumroll2.png</a>})
