Could allowing the use of your photos for free actually be a way to increase income? Portrait photographer Jonathan Worth — the man behind Coventry University’s free photo courses — used to send take-down notices to any website that shared his work without permission. Then he met author Cory Doctorow, a proponent of Creative Commons licensing, who suggested that he try giving away his work for free. Worth then made a high-res photo freely available online and quickly sold 111 signed prints, netting him £800 (~$1,270).
I really doubt that the rippers will send me a portion of their ill-gotten booty.
