You should check two things. First, JCE settings. Second, what are the Text Filters in the site's Global Configuration for all of the User Groups your user belongs in. This is the fundamental way Joomla works. The editor sends some HTML and Joomla filters it based on the Text Filters. If the user group's text filters are set up to strip tags then, yep, the image tag will be stripped as well. People tend to forget about this because plain old users (Registered or Guest) rarely post HTML content in the front-end unless it is submitting articles, support tickets or comments.
