What has happened with the button icons. I've got Firefox 3.6.13 on 2 computers and on both of them I started noticing a problem with the button icons. Instead of the icon showing up I now am not getting any of the following buttons...
"Go Back" http://images.ibsrv.net/ibsrv/res/sr...bits_start.gif
"Go to first new post" http://images.ibsrv.net/ibsrv/res/sr...s/firstnew.gif
"Go To Last Post" http://images.ibsrv.net/ibsrv/res/sr...s/lastpost.gif

The link to the image icons doesn't even pull up a picture in Firefox, but this works fine in IE. Not sure what has changed, but the icons were there last week and now I've got the same problem two systems.
