Event Calendar Advice

Hi there
I need help on this one.
I’m looking for an plugin that allows me to post events that would be very customizable. I need to publish gigs, and I would like to be able to add the gig’s flyers to the entry of each event.
Right now I’m using wp-ng-calendar, that one based on google. which mostly works pretty fine, except for some little details and the fact that I can’t add images or links to every entry.
Is there any plugin you can recommend me to do this?

thanks!
