It's Tuesday again....

It's time for a terrific tip....but I was wondering if anyone had one for me??? I am really interested in getting this blog all fixed up! I would LOVE to know how to add pics to a post...you know, how they are actually in the text of your post? I would also love to know how to change my layout...so it's not so generic. I see all these beautified blogs and I only see the option to use their pre-made templates. I realize I am missing something...so anyone got a tip for me??? :)
