Images not showing in IE

I have a small problem.

I have two domains .com and a .co.uk which both point to the same web folder.
Now when a user looks at the site and uses the .co.uk address the images show up fine. But when the look at the site using the .com address then the images don’t show up and leave the annoying little red cross box.

Now looking at my code everything looks fine here is and example:

<image src="…/default_image_folder/banner.gif" alt=“top banner image” />

I’ve tried refreshing the cache and restarting IE but nothing images aren’t either seen or loading in.

In all other browsers they work and i can’t tell the users to upgrade to another browser.

Anyone else seen this or have and suggestions?

I did think having a full URL to the image for example:

<image src=“http://www.somesite.com/default_image_folder/banner.gif” alt=“top banner image” />

Any ideas
