Image links not updated after Moving WordPress directory

Hello friends,

I recently tried to change the installation folder of my WordPress site from “root/blog” to “root” of my domain. But after successfully moving it via GoDaddy control panel, I realized my old posts on my blog weren’t loading and were showing internal server error instead.

I googled a bit and fixed the .htaccess file by manually updating the domain address in it. Now,all posts are showing up but my images still aren’t loading as they still have old address in the database.

Is there any way to update the address of images automatically as it would take so much time if I have to do it manually. Any suggestion would be appreciated.

Thanks.
Rohan.
