Custom Wordpress Image Slider Plugin

**Important Note: This is a BEER CAN historical website. We do not sell or advocate the use of alcohol. However, we do encourage collecting the cans and learning the history. The work I need: We use Wordpress 5, and Shopperpress 7 The posts have been renamed 'products' and we do not use the featured item, or picture attachment. Instead, we use a Custom field inside of the products form, to add the image name. I'm presuming that Shopperpress displays this image from that location, as it is definitely not attached. I've tried several sliders - and they work to pull the post data - but never pull an image. I need: An image slider, similar to the placid slider by slidervilla - demo at [login to view URL] I purchased their placid one, and it doesn't work for me - but if you could get it to work instead of making a new plugin, that would be great. I've attached some files that show the fields in our product form. Please let me know price and time in your bid. Thank you.
