wrong spacing on Macs

[bbwalker]

I have a webpage up that looks exactly like I want to on a PC (Windows 2000, IE 6.0), but on a Mac there is unintentional vertical space between the "headline" images and the html text underneath.

Can anyone advise how to eliminate this (short of banning all Macs?)??

Thanks!

Addendum:
Any advice on how to maintain horizontal spacing but eliminate the vertical spacing that shows up on non IE browsers (be they Mac or other)?

Thanks!
