As the going premium of the Aeros Theme caused some confusion, I've renamed it AeROCKs. It is the professional version of Aeros with more functions and much better optics, as well as professional and quick customer support. There is also a new preview site for AeROCKs with some of its background image options - of course you can use your own image - just examples. Here's a screenshot of your background image switcher:

So if you want to add first-class optics and features to your blog - as well as get my help for setting it up or even customizing it - consider buying the AeROCKs Professional WordPress Theme, thanks!
