the process gary is talking about probably uses Photoshop using
SELECT-COLOR RANGE tool, followed with FILTER -OTHER -MINIMUM. It would pay also to use a feather if you want to try this process, SELECT -FEATHER. it takes a bit of fiddling to make it look natural. Heres a thought for you to consider, what appears as wrong, or noisy or not natural may not show up when you resize it to the 200kb limit

Thanks Alchemy that sounds like what I read although I seem to remember the article going into rheems of detailed instructions that prompted me to put it in the too hard basket at the time. Thanks again for the tip I will give it a go, and ofcourse thanks again to you Gary.
