Okay, here are a couple tips...
First, not sure where you are getting the HTML for your pictures, but the appear to be going into a Table and that table has a STYLE applied to it.. In order to get rid of the border (the usual tag) around those pictures you'll either need to remove the section in your HTML that refers to the table style, or simly change the border from 1px to 0px. Do a search in your HTML for 1px and you'll see what I mean...
Also, as for changing the font "FACE" you'll want to make sure that the face you want is available on the users computer...otherwise it won't display...
Here's a good article where they discuss that:

I'm not quite following what you want to do with the images...
I see two images on PracticeBoard one of some books and the other being your rose image.
Did you want those two on the same line?
Which one on the left and which one centered...
Sorry I just didn't grasp what you were going for on that one...
