Image Code not showing in exploer 6

Whilst I can see the image code working fine my client who uses internet exploer 6 does not get a box appear with the code in place. Has any one else had problems with explorer 6. Could it be a font thing?

Link to the site is below.

Works fine on IE6 and Firefox 2 here. The image you are seeing means your host does not have GD compiled. GD is what PHP uses to generate images. The image you see is actually made up from a colletion of premade images that were turned into strings.

I've spoken with my host and they have GD compiled. Is there anything else I can do to make this work.

Your site also works fine for me also. Using Firefox and IE 7. I would say it is some setting on your pc or the other that is blocking anything for you.

If you have GD I don't understand why you are getting the basic GD and not the advanced version.

Its's GD Version bundled (2.0.28 compatible). Is this any good?

Can I upload anything that will help this to run smoother or does my host need to change the server settings.

Thanks for your help with this.
