Are you sure the path is correct ? Check if the file wp-content/themes/premiumnews/thumb.php is there and if it have permissions to execute (try to CHMOD it to 755 or 777). Also your host might not allow you to execute this file due to used functions.
Network Error (dns_unresolved_hostname) Your requested host "www.quicknrandom.info" could not be resolved by DNS. For assistance, contact your network support team. I can design wp image gallery pm me for details if u need
There seems to be a mod_security problem with the TimThumb script and a few hosts. http://code.google.com/p/timthumb/issues/detail?id=8 You can either ask the host to fix it or try removing the domain from the path.
Thanks guys, I think i'm just going to remove the image gallery totally and put in the featured content gallery in its place. that seems like a much easier solution right now. I'll post back on my progress
