I sell original photo from harveysphotoart.com. Any selection has three additional "you may also like" selections offered at the bottom of the page. They don't change randomly to show the extensive variety offered in my collection. Instead they offer the one viewer selection and the same three choices below. Is there a way to change the bottom three to show more of my collection? Thanks!
The shown products are determined by the theme you're using. Some just pull products from the same collection, and others give you more control.
There are also some apps that give you more granular control.
What theme are you using?
If you'd like, I can take a look and see if we can find a solution. Send me an email at email@example.com.
