Lost Thumbnails...help!!!!

[nyt84]

Hi, I have a serious problem with my gallery and I need help. I do not know how to describe the problem but I will show it to you.
http://gallery.greensg.org

You will notice that i have lost some thumbnails in my randoms file, most view or any other places that have thumbnails list. I have tried to rebuild the thumbnails but still not use. It is not a broken image link but it simply jus wont display the thumbnails. The thumbnail is being created and I have checked the link. I have tried overwriting my coppermine installation with all the stable 1.3 CVS files but that doesn't help to solve the problem. This problem juz came all of the sudden when i woke up in the morning to check my gallery. Could it be my gallery hacked? Anyone familiar with this problem please help...Thank you!!!

I had no problem.  the site looked fine to me. 
The thumbs are not done dynamically, so re-building them will make no difference.

Are you having this problem with different browsers?  It may be a timeout problem.
