Image not loading properly

Hi,

I recently migrated my site http://www.stuff2share.com to different host. Now the problem is, the tumbnail image in my site is not loading. the image url is like this,

http://stuff2share.com/wp-content/themes/eNews/timthumb.php?src=http://www.stuff2share.com/wp-content/uploads/A-Ladder-of-Swords-207×300.jpg&h=74&w=74&zc=1

but when i logged into admin panel, and try loading the site, that time it is loading properly. when i checked the image url, it is showing like,

http://www.stuff2share.com/wp-content/themes/eNews/timthumb.php?src=http://www.stuff2share.com/wp-content/uploads/A-Ladder-of-Swords-207×300.jpg&h=74&w=74&zc=1

once i logged out, then again the image is not coming up.

both my site name and site url is http://www.stuff2share.com in wp_options table.

the only difference is “www” in front of my site. Any one please help me to sort this issue?
