Any digital artist worth their salt should be capable of making a crisp 200k image given decent tools. Best approach: render much bigger than needed, save from Poser as tif or PSD. Resize in Pshop. Use Photoshop's Save-to-web to save it to jpg. USE the compression in save-to-web. I've used as low as 35 and still gotten crisp results. Poser's jpg export is terrible ..avoid it :) If you absolutely MUST post larger images you can post in the gallery ..which after all, is what its for
