Wordpress all image's path change

Wordpress all image's path change

in my wordpress site suddenly something has changed and all the images of
the website and blogs are not displaying instead image not found is
appearing.
After checking the images path i found it as below for a single image.
<img
src="http://www.azraar.com/blog/wp-content/uploads/2012/02/mysql_logo.png"
title="mysql_logo" alt="" data-imgh="340" data-imgw="930">
actually this is wrong, (path) it should be as following
http://www.azraar.com/wp-content/uploads/2012/02/mysql_logo.png (/blog/ is
omitted)
Then it does point to correct image. so i am wondering how can i change
the entire images in my website to load without the /blog section in image
path.
I also checked the db of wp.. found the postmeta table contains these
images paths info but it doesnt contain in the entire paths.. it only has
like this for all images.. 2012/02/mysql_logo.png
any workaround for this ?
