Changing Buttons
 

I am having an issue I am hoping someone can help me with. I picked up a nice set of custom buttons for one of the custom styles on my forum. I set up a separate folder on my server just for these buttons and applied it to the theme under the theme manager just like the User Manual prescribes.

My issue is that I am the only one that sees the new buttons on the forum. Everyone else sees underlined text with a little white box with a red "X". Any ideas as to what it is I am doing wrong? I checked the Properties on each .gif on my server and they are all linked to the server. I am lost... :confused:

Thanks in advance for your help!
