Check out FFXporter! It's free...

It's an excellent plug-in but a tad expensive.
However I'm pretty sure I'll buy it.

$20 is a bit much. But this is a super solid add on to iPhoto. Saves tons of time.

Makes it so painless to keep your photostream current.

I still use the old freeware version. The new version is great, but it still lacks some features like adding a photo to more than one pool or set.

I can't live without this one. Gladly paid for the 2.0 version.

This was the one reason to get a flickr account. Without iPhoto support I would not have been interested in flickr. This guy should get some money form the flickr guys (i.e. Yahoo....)

THANKS!

Fraiser (developer) is very great with support. The 2.0 ($) version is well worth the money.

The older version is freeware :)

this is golden.
