I agree with Achilles that donating photos that are similar to others in your portfolio helps increase views and hopefully sales of said subject. I have been donating photos recently and usually have a slight increase for similar, or same subject (cat,horse,whatever) for a few days. I think it also helps to give exposure to all you subjects. I see more n/a 's on unrelated subjects, so I guess some buyers take a look at your whole portfolio at the same time. posted in Donated my First Image ---> 10/17/09
