I was talking to Francie from FB and she brought this topic up. If you need to put an inline image in a question (typically this would involve a screenshot or an image of a product) and then ask a couple of questions -- It's kinda cumbersome to do this now.
1. Users don't know HTML and need to learn IMG tags etc.
2. Users think they need to upload the images on their own servers - That may (or may not) be easy and feasable
One option can be to provide an icon specifically for images and have a couple of options of displaying the images inline (like the Bold, Italic etc.)
