Image and file uploads are now enabled when asking questions. To upload an image, click the image button (beside the Code Snippet button), and click the Upload tab. Files, like spreadsheets, can be uploaded using the Upload tab in the hyperlink menu.
We've also added support for tables, which can be helpful when discussing Excel spreadsheets.
Folks who like to write their comments using HTML now have that option using the "Source" button.
You should see all these new options when posting questions, answers and comment.
