Hello. As you already know that about all themes have this script at Wordpress. I had it too but one day I started to end up with a lot of images being actually replaced by a smaller image with title "timthumb.php" A wise guy told me to block that script's location by robots.txt, I did that and it went fine then after. But I still see some of the timthumb stuff indexed in Google images, however this time, my actual images are not getting replaced. So I just wanted to know if that's fine since that could just be due to the cached version of the image at Index page. Also, what do other websites do to cover this up, I see very top sites and none of them have something to block timthumb.php in their robots.txt and nor their images in Google show any such thing like that. What do they do ? My Google adsense site diagnostics, shows a lot of images being blocked by robots.txt which I believe are just timthumb images so thats not a problem too right ? Google WebMasterTools doesn't show any such thing like that though.
