Google Map sizing

[gooner67]

Hi

I have added map links to my images, but the maps always open in portrait rather than landscape, and I can't seem to change their size. I want them to open as landscape and be 800x600, but nothing I do in the settings seems to help.

You can see what I mean by clicking on the map icon in the images on this page

Can someone post an image showing the settings in the correct positions for me?

Thanks in Advance.
