What is the best way to share wireframes with clients?

Is there any way to export my Omnigraffle wireframes to HTML? If not, what is the easiest way to share my wire-frames with a team or with an external client?

BTW, this seems like a pretty basic topic but I couldn’t find anything on it. Feel free to point me in the right direction if there’s already a resource on this.

Thanks!

PS. Trying to edit a typo in my original post and keep getting the error (Body is too similar to what you recently posted)…whaa!!?
