Site displaying differently in 3 different browsers

[st00dent]

Hi, a friend has asked me to help them with their website, but it is displaying differently in Opera, Firefox and IE, can anyone see a way to make it work properly on all three? (The way it appears in Opera is the way it's meant to look)
The problem is with the phone number image at the bottom right.
Here's the link.
