Issue with PHP curl and GD extension

Hi
I am new to OpenCart, yesterday downloaded the latest version of OpenCart and setup the WAMP server on my windows machine. everything was fine but when I started configuring Open Cart.... it's not able to load the curl and gd extension for php. I tried all possible ways I found over net, but nothing works.

Appreciate your help.

Thanks
Dinesh

Did you enable it in your wamp settings?
