In my Wordpress theme thumbnail images are automatically get cropped .All my images are large size and so my thumbnails show only a part of the original image.
I searched in internet and found an article
http://www.binarymoon.co.uk/demo/timthumb-zoom-crop/.
It says No cropping will occur and it will adjust automatically to fit the container size if if we set --zc = 0: Resize to Fit specified dimensions (no cropping)-- like timthumb.php?src=atlantis-dock.jpg&zc=0---
But i don't know how to implement it in TimTHumb.php.
You guys kindly help me to do it.
