Newsletter Plugin Not working

Trying to use the e-Newsletter plugin.
The plugin will not let me insert images into the content area?
Also, is there a place where I can manually add and enter clients email addresses?

Just a comment on improvements: Under "members/bulk actions" this option should be on the top of the page as well as the bottom. It's very inconvenient to scroll all the way to the bottom of a long list of subscribers if viewing "all" your contacts to make bulk actions.

Thanks
