Image and menu alignment

Hopefully I’m not asking a dumb question, I’m sorry if I am.

My blog is incorrectly aligning my images. The odd part is that the body text is aligned correctly and every post from before I actived WPfolio is correct. I’ve read every line of the php and css files. I don’t know very much about coding so it’s a struggle.

I’ve changed every line that said “align:” that I could find and did have some effect in different places (obviously my header and a lot of different things on the rest of my site, alison becca)

I thought maybe there was an error in the individual posts html so I checked. Here is the line for one of the pictures that I wanted to be centered in the blog post:
<p style=”text-align: center;”><img class=”aligncenter size-full wp-image-375″ title=”alison becca wedding je 2″ src=”http://www.alisonbecca.com/wp-content/uploads/2010/10/alison-becca-wedding-je-2.jpg&#8221; alt=”” width=”605″ height=”447″ /></p>

Am I out of luck?

(Also, two quick questions. Why is my body text black when my font color selected is #EBC88B? I don’t see that font color choice taking effect anywhere. And, where is the line in the style.css file for making the menu center aligned? I changed it in my last version of WPfolio but can’t find it in the newest one. Yes, I know I should be using a child theme but those are way too confusing at the moment. I have read all the help pages. I’m trying to learn as quickly as possible!)

Thank you sooooo much for taking your time to help. Someday I’ll pay it forward once I get the hang of this a little better.
