ok, nice and easy (and yes, I've done this in 2.3 to make sure it works for you

)
in your body tag section of your font/colors/images page add the following to within the tags there
Code:
style="background: url(http://www.silverstangs.net/images/background13.jpg); background-attachment:fixed"
Delete the contents of the following boxes
page background color
table border color
category strip background color
table header background color
first alternating table background color
second alternating background color
calendar background color
This makes everything transparent and just displays the text and images and the box around today in the calendar.
I used the background image from your myspace page, so if that is not what you want to use, just replace the image url in the body tag code.
