Buying Simple php Image url resize for wordpress

Hi,

I need a simple php script to resize images for facebook og:image

Ex img url:

<meta name="og:image" content="http://www.hdmusicvideos.info/thumbs/Brotha%20Lynch%20Hung%20-%20Meat%20Cleaver.jpg" />

Code (markup):

(width 156px height 103px)

I need something like:

<meta name="og:image" content="http://www.hdmusicvideos.info/ogimage/image.php?src=http://www.hdmusicvideos.info/thumbs/Brotha%20Lynch%20Hung%20-%20Meat%20Cleaver.jpg" />

Code (markup):

In image.php I want to set image width & height manually...ex: (width 256px height 203px)

Than convert the url via htaccess to:

http://www.hdmusicvideos.info/ogimage/Brotha%20Lynch%20Hung%20-%20Meat%20Cleaver.jpg

Code (markup):

 

I need something like this: http://revisedagain.com/2011/custom-rewrite-rules-with-wordpress-timthumb/
