(It's rnrholmes here but I'm on a different account right now:)) basically when I go to click on upload it just doesn't open up anything for me to choose a thing to upload. Same goes for the background. You know when you hover over them the cursor changes to the hand thing telling you that it's a link, it doesn't do that, it's just like I'm clicking nothing?
I have no idea why it does that, but there is another way to add a header image. Just look through your code for this
id="header">
and then exchange only {image:headerimg} for the URL to your header image (you have to upload it somehwere first, obviously, like a private post on tumblr or photobucket or something). Just note that this way you won’t be able to edit/upload the image in the Appearance tab in the future.
The same goes for the background image, only then it’s this bit in the code:
background-image:url('{image:background}');
and make sure you really only change {image:background} for the URL and nothing else
