Add the image as an attachment.

Adding images to a post becomes complicated with a rich editor.

I think the best way to add images is to attach them to the bottom of the post, like canny.io does.

Also, integration with a third-party image storage service for managing added images would be great.

Adding images may as attachments may be something thats added in future if there is more community demand.

On the third-party image storage it is already S3 compatible for which there are many providers out there. In the upcoming managed cloud version of Quackback the image hosting will be provided as part of that service, taking away that hassle.
