how can i add multiple logos in my header

ive tried everything and even editting css.

how are you adding the second logo? and how did you add the first (i see an image)

i just hit design and appearance and there is a thing i can select a logo. and thats the issue i dont know how to add a second one, also i cant even center the one that i currently have.

i see, there is usually one place where you can enter a logo.What you can check is your appearance>widgets and see if there is any sidebar for the header which you can use to enter another image if this is what you want to do.

any idea how i can center the image that i have there?

you can try this

#cc-header .span7 {
    width: 100%;
    margin: 0 auto;
#cc-header #register {
    float: none;
}

enter this code at the bottom of your style.css and see how it looks
