1. Upload your new gateway icon to your theme’s images folder.
2. Edit your theme’s function.php file in a plain text editor and add the following new function>

   function mythemes_icon_cash() {
   	$icon = array(
   		'path'=>get_stylesheet_directory(). '/images/cash.png',
   		'url'=>get_stylesheet_directory_uri(). '/images/cash.png'
   	);
   	return $icon;
   }
   add_filter('eshop_merchant_img_cash', 'mythemes_icon_cash');

There are also filters for each of the other gateway icons:

eshop_merchant_img_cash
eshop_merchant_img_bank
eshop_merchant_img_authorizenet
eshop_merchant_img_payson
eshop_merchant_img_paypal
eshop_merchant_img_ideallite
eshop_merchant_img_webtopay
eshop_merchant_img_ogone
eshop_merchant_img_epn

Enjoy!

Answering and checking off the following question before you start configuring eShop should make the eShop set-up process a little easier for you.

Is Your Merchant Gateway eShop Compatible?

There are a number of merchant gateways that you can use with eShop:

• Authorize.net
• eProcessingNetwork
• iDeal Lite
• PayPal
• Payson
• Ogone
• webtopay

But you may need to make changes to your gateway account to ensure that it is compatible with eShop.

Do You Have Your Merchant Gateway Details?

You will need all of the necessary details for your chosen merchant gateway – e.g. if you’re using PayPal, you will need the email address that you use on your PayPal account.
Setting up eShop merchant gateways

Where Will You Be Shipping To?

Will you be selling in your own country only (i.e. by State/County/Province)? Or internationally (i.e. by Country)?
Defining your shipping locations

Have You Zoned Your Delivery Locations?

The cost of shipping an item varies according to its destination. eShop allows you to group different delivery locations into “zones” & apply different charges accordingly. You can have up to 9 zones.
Have you divided your shipping locations in 1 or more groups – called “zones”
What are shipping zones?

Have You Broken Your Products Down Into Shipping Classes?

The cost of shipping an item can also vary according to its weight, size, cost or fragility. eShop allows you to define up to 5 shipping classes to accommodate these differences with the 6th reserved for free shipping.
What are shipping classes?

What Are Your Shipping Costs?

You should have worked out all of your shipping charges and have determined how to apply them.
Will you charge for the first item based on delivery zone & shipping class with a reduced cost for additional items (Method 1)?
Will you charge for the each item based on delivery zone & shipping class with no reduction for additional items (Method 2)?
Will you charge a flat rate based on delivery zone only (Method 3)?
Will you charge based on delivery zone & product weight (Method 4)?
Calculating shipping

Will You Be Applying Tax?

If you will be applying tax to products – such as VAT or sales tax – you will need details of what tax to apply and when. You also need to decide if tax will also be applied to shipping charges.
Setting up sales tax

Will Your Products Offer Choices?

eShop includes option sets that allow you to add customer-selectable choices to your products. What options can customers choose from when purchasing one of your products? Different sizes? Different colours? Are some colours more expensive? You can set an additional price & weight for each option within a set.
Using option sets

Do You Have All The Details And Images For A Single Product?

You will need all of the text plus at least 1 image for a sample product. You also need to be able to set it’s price, shipping class, options set(s) and tax rates based on your answers to the questions above. This exercise will help you get a handle on how to set up eShop to suit your needs.

Thanks to stug2000 for bringing this to my attention. How everyone else managed to miss it over the last 8 months is completely beyond me!

Emporium supports the aside, gallery, image, quote and status post formats. The theme’s post format documentation also includes some examples of how you might use some of these formats within your online shop.
