Welcome to Mibba. Making a fancy layout to begin with will be complicated, you'll soon get the hang of it. To learn how to create a layout you can visit http://www.mibba.com/forums/view/Mibba/Profiles/ This area of the Forums is all about profiles, so you'll get lot's of help.
WHile you're learning, you can visit http://www.mibba.com/forums/topic/88738/ thread. Here you can find websites created about Mibbians and others who have pre-made layouts you can borrow.

I only make CSS-based layouts so I can only tell you how I do those. xD
Basically you just set your profile up with a basic CSS layout and then go into the CSS box (My Mibba > CSS [on the right]) and play around with it. The hex codes are pretty easy to fool around with. Just open up another tab with a hex chart in it so you know what codes are what. Then just find the links that the original layout used for pictures and replace it with your own. It sounds a little complicated, but it's not. :3
