I have no idea what I'm supposed to be looking for on this page.
That's ok, you guys win. I'm giving up and will search for different software since Oxwall does not seem to be user friendly at all for beginners.

Doug, I recommend you to take your time and go through the user manual first: http://docs.oxwall.org/overview:user_manual

Hello Tammy ive read the same article over and over again, and still i had no succes i downloaded the sign in html file and hand coded the background image. I followed the steps and still no effect. I used my cms and still no change its seems like all i can achieve is to change the background color i even ploaded my desierd image via cpanel in oxwall and in my main domain and still no effect. Ive cleared the cache a million times in and out of dev mode, what am i missing?

Upload the image in admin themes edit images and link from there

Please provide step-by-step instructions what you do and where, as well as the code Akeem?
