Hello! Let me first say Thank You for designing such a wonderful WordPress Theme. I've found it's usability and usefulness to be unparalleled.

I'm using Atahualpa 3.1.9 and have created a custom header image. This image displays perfectly using Internet explorer but not at all with FireFox. Here's my url: www.eathealthyanywhere.com

Any ideas what the problem might be?

You have a space in the image file name:

Header 2.jpg

If you remove that space it should work.

Success! Thank you so much!
