They really need to make their instructions clearer when it comes to adding product options in regards to images. Easy enough to add options for checkbox or drop down but no clear way to add MULTIPLE images for the consumer to choose when ordering a product from in their help section. Would suggest that they add a section for this.

Our product options get placed where your product options are located in your theme. For your example this is a very tight area. If you want the options in a custom location please reply to our email and approve our request for access to your site.

We tried all of the product option apps on Shopify. This is the only app that made adding hundreds of variants to each product as painless as possible. We have some custom items with 300-400 variants each. With this app, you can add the variants by a comma separated list. The other apps do not do this (Bold Product Options was painful). Also, you can set it up to have the price change on the product page. The others did not. Technical support is great as well. I had an issue where the custom product options were not displaying in the cart. Martin hopped in the store and fixed it, quickly. This is a great app!
