Attribute image layout styling

I am trying to get the attribute images to look like the also purchased layout with the dotted lines - this is as far as I have managed to get:
***/test-store/index.php?main_page=product_info&cPath=105_19_20&products_id=25

I can't get rid of the far right vertical line at the end of each row, or the top horizonal line.

I have achieved this with edits to:
includes/modules/CUSTOM_TEMPLATE/attributes.php
includes/templates/CUSTOM_TEMPLATE/templates/tpl_modules_attributes.php
includes/templates/CUSTOM_TEMPLATE/css/stylesheet.css
includes/templates/CUSTOM_TEMPLATE/css/stylesheet_dotline.css
includes/templates/CUSTOM_TEMPLATE/css/product_info.css

Any help on the final hurdle would be greatly appreciated

Hi - Did you try this?
.product-divider {/* border-bottom: 1px dashed #CCC; /}
or this
HR {height: 1px;margin-top: 0.5em;border: none; / border-bottom: 1px solid #9a9a9a; */}

Sorry I didn't clarify that my issue was with the dotted lines.

I added the dashed lines using the <hr class="product-divider"> to the attributes area,
I'm having the issue with the dotted lines that are dividing the attribute photos. I'm trying to mimic the look of the "also purchased" below that.
I don't think I can actually do that with out some major re-coding of the attributes module, although I have a few ideas brewing...

If you are looking to mimic the "also purchased" style... You can add this module:

Then you can add dashed lines simpler.

Hope that helps,
(and saves you some time)
