How do I make this so the site displays the same in Safari as it does in Firefox and IE...

In Firefox the site looks like this Firefox Style

Yet in Safari it looks like this: Safari Style

the Ubbthread style originally installed which was used as a template looks the same in both? is there a line I added or missed that would be reasonably easy to spot? or fix?

And part two... Avatars.

In my Avatar folder from UBB Classic I had "X" amount of avatars, none of which appear in Threads. In order to add avatars I have to do it one at a time from the control panel. Is there some way to add them to the avatar list without having to do it one at a time ?

thanks,
