Event Calendar Plugin

Did you find one? I’m also looking.

You could use Event Calendar 3. It just isn’t supported really anymore. There are some fixes for some bugs that you will have to track down to get it to work properly. It basically uses regular posts.

check out the mail list or sourceforge for some of the fixes.

You can insert images into your regular posts, event calendar plugin uses these posts.
