Images missing but only for some users

[NinjaKane]

Hope someone can help on this, I am missing a thread icon, thread_dot_lock.xxx but only for some users. We have tried this on multiple machines and OS. Both users are of the admin group but it shows up when one user is logged in but not when another is logged in. very strange. hope someone can help!

Did you check if this happens in the vbulletin default style as well ?

I dont think it does, you can hit the missing image via url, and as I said it only happens for some users. All I did was use a rewrite rule to change .gif's to .png's site wide. the image is still named the same though.
