Well, maybe we can stop him from leeching from our site! We can put an image with letters, so that you must first write those letters in before download (ofcourse letters will always be different).[/b]

...and as has been discussed elsewhere (see the DFL thread I linked earlier): CAPATCHAs are worthless in this context. Such measures are useful for for preventing the most casual of leechers; however it is relatively easy to plugin and tune an OTS OCR package that defeats the CAPATCHA automatically. Hell, even randomizing the location of the file is pointless (I could write something capable of screen-scraping the site for the "dynamic" download link in a few minutes).
The only end-result of adding CAPATCHAs is a number of irritated end users whom have to compete with bothersome access control mechanisms. Oh, that and they are just a bid of a hindrance to the visually impaired.
