Piglet plugins or how Lightroom export plugins can be stacked
Tim Armes' LR/mogrify plugin and Jeffrey Friedl's flickr/smugmug/zenfolio plugins just became orders of magnituse more useful as they devised a way to make them work together. Now you can watermark, add borders, sharpen, and upload to flickr, all in one fell swoop, directly from LR's export module. Check it out here. Big applause to these guys. Excellent work.
