Center PayPal logo on sidebox and remove line

How do I remove the line under the PayPal image? And how do I center the image?
I can't seem to figure this out.

Thanks

The line is here:

.sideBoxContent img {
border-bottom: 1px solid #b2b1b6;
}

Add this to center the image:

.sideBoxContent {
text-align: center;
}

To center the image add this to your stylesheet

Code:

---

#paypalcreditcardssidebox {
 text-align: center;
}

---

Thanks!
