Hello Devine721,
Thank you for your response.
By default, there is no such option. You can post a request to our dev team via this page – https://www.8theme.com/taskboard/
If it receives enough votes from other customers, our development team will consider adding new settings in one of the upcoming updates.
Right now, the next custom CSS code can be used to change the size of thumbnails:
.single-product .swiper-container-grid .swiper-slide {
padding: 0px !important;
border-radius: 100px !important;
max-width: 10px !important;
max-height: 10px !important;
margin: 5px !important;
}
(Theme options > Theme custom CSS > Mobile area).
We hope this information is helpful.
Best regards,
8Theme’s Team
