Fix sidebar testimonial widget

Hi WordPressers,

Hopefully you can help me. I am looking to fix the alignment of a rotating image in a sidebar testimonial widget on my site.

Here is the code for the content block.

<h2>Our Pest Control Customers</h2>
[testimonialswidget_widget category=customer-testimonials hide_content=true hide_source=true hide_title=true refresh_interval=1 order=asc height=188] <a title="Our Testimonials" href="https://www.rjspest.com/index.php/customer-testimonials/"><img class="alignnone size-full wp-image-381" src="/wp-content/uploads/2014/06/readtestimage.png" alt="Read Our Testimonials" width="186" height="28" /></a>

Thanks in advance,
Mike
