Thanks for you nice words, I’m glad you like WP-Lister. ??
I had plans to create additional listing templates – including one using a javascript zoom effect – for over a year now, but still haven’t found the time… so right now, I’m afraid I can’t help you, but you’re welcome to contact me at https://www.wplab.com/request-support/ with login details to your site and I’ll have a look at what you have done so far, which zoom effect you’re trying to use and how I can help you to get the required javascript working.
Regarding you last question, I’d also recommend to submit a support request on wplab.com – with a link to an example item to investigate and a detailed description of which images you want to show. WP-Lister already shows all images from the WooCommerce “Product Gallery” by default – if that doesn’t happen on your site, I can only assume there is something wrong… something that I need to examine first hand to be able to help you.
kind regards,
Matt
