Heh
Well I am not familiar with this skin, but I can see the default logo is a Flash file. I know a bit of Flash, but the easiest solution would be for your site admin to go into the skin's (BBTech) template and look for that .SWF file. Either make a new one that fits those exact same dimensions and just replace the file on the server, or change out that .SWF file for a JPG of GIF static image that is the same size.
The one problem you are going to have, but easily fixable if you have someone that knows Photoshop (or other editor) will be matching the background of the header strip (heh, I said strip

) with that of the logo bar.
Reply back if you want me to take a stab at it. I can get some files from this site (or point me to the official ones) and put them in Flash and export as a SWF and you can just drop the file in. I dont have time to get all fancy, but just getting something up might help (if you are concerned about it). Would only take a few minutes.
Take it easy, fly safe.
