Part of my header not showing up

[excalibur300]

yeah that would work, problem is i have several themes not just gospel grey.

so i need some sorta fix that would be dynamic, so all the themes that need tile_back.gif will look right.

Also i did go through MyBB community first and labrocca "tried" to help with this but couldn't figure it out and was kinda rude about it too, anyway i talked with incadude and he suggested i talk with you, he said you could probably fix it.

I have been worrying with this and the logo for about 2 weeks now, so if you could help me out, id be much grateful.
