Forum header script works only in IExplorer

[dieselpower]

Hello, I am being in a way insolent by seeking help for a script that doesn't come from your site, guys. For this I want to apologize. I'm quite desperate .

I am not even sure what type of script this is. I am helping build a proboards forum and using an old skin with "Global headers and footers" script. It is posted below.

Link to the forum site, for you to preview: http://liquidfleet.proboards.com

3) Describe problem:

The main banner at the top doesn't load in Firefox and Chrome, only works (seemingly) without mistakes in Internet ExploDer. On certain pages of the forum frames of unloaded images appear in Firefox or Chrome.

I need help to make this a script that functions under current standards and doesn't bug up in browsers other than IE.

Thank you in advance for your help! Sorry for posting the link to a DD script, although it's not a DD script I'm having problems with.

Regards,
