Post thumbnails problem

Hello. I’ve moved today my site from one host to another and everything seems ok except that post thumbnails are not displaying.
Every other photo shows up as it should after i’ve added some sql query:
UPDATE wp_msposts SET post_content = replace(post_content, ‘olddomain.com/e/blog/wp-content/uploads/’, ‘newdomain.com/wp-content/uploads/’)
Any idea what could be wrong?
Thanks!
