Secret behind getting the hits is teasing. Showing something that will arouse imagination. Red color is good one. Basically if you have deep, not too bright colors in your pic, include it to thumb. Show something intresting. Some detail that makes think, what the hell is this pic and why? One may have the most beautiful sunset, and the worlds most beautiful place where she/he proposed her/his wife, but when only rezising pic to 200pix, the thumb will look boring. And, at the thumbnail galleries, nobody really dont care about the names of pics, so words in thumb are good too. Stronger the word, bigger the intrest. Versionthirteen was the master of thumbs, sad he pulled his works away. .n ps. I'm using huge breasts and text "Syyd" written on 'em, works better than 1000 angry rabbits. Bigger the breasts, more the hits. Yeah.
