Browser compatibility issues

Dear Forum

I have just published a websire for a client, she is very happy with it and for my first site I am too. its a set of html pages that contain a small image gallery, some static images and links. My client has just bought a MAC and she says some of the images seemed to have shifted up the page a little. I have downloaded safari to my pc and she’s right, IE displays some of the images a little lower down the page.

These images are all in tables, i created the pages using MS front page.

I’m really gutted as I have just finisehd the site and I really would like every one to get the same resukts no matter what browser.

Cany anyone help me, is it something simple?

Many thanks

Joe
