Custom Header (HTML, not just a single image?)

[psoexplorer]

I'm trying to add a custom header to my forum - I know how to add a single image for a logo, but I want to add the header from my site which is a table of images and a bit of flash.

When I try adding this html to the header section in the custom style, it looks like it's going to work, but doesnt. The images have the box there to show they're loading, but they all just dissapear and everything moves up as if there was no image code there...

The flash works, and the text that I put in it, it's just the images that dissapear.

Any idea??
