Attach files in this forum

I have a question about installing Think or Swim in Zorin. I want to attach a copy of a screen shot that I get when trying to install TOS.

Is it possible to attach a file to a post in this forum? If so, how do I do it?

There is a toolbar at the top of the post text box. Click the 7th icon from the left (the one that looks like a small picture of a mountain) and it will trigger a "Add an Image!" popup. Choose your file then click "Upload".

I believe you can also drag an image file straight to the text box as alternative to choosing a file I mentioned above.
