Add more banners right side JM Wall

Hello.

Can you help me how to add more side banners under existing banner?

Banner(sale up to 70%) under.

Dear steveyoon03,

Please open file app/design/frontend/default/jm_wall/layout/catalog.xml and duplicate

Code:

<block type="core/template" name="right.permanent.callout" template="callouts/right_col.phtml">
                <action method="setImgSrc"><src>images/media/col_right_callout.jpg</src></action>
                <action method="setImgAlt" translate="alt" module="catalog"><alt>Keep your eyes open for our special Back to School items and save A LOT!</alt></action>
            </block>

after that change src, alt.

Thank you so much!
