I have pictures from last night's gorgeous BH at Stone Barns dinner I'd like to post. How do I do that without loading them onto a website first (i.e., direct from my CF card disc or computer)?

I'm afraid you'll have to load them to a website first. A free picture host is suggested here:

But then just click the IMG button, paste the URL for the photo, click OK.
