Hello,

Thank you for your decision to work with our theme.

As for the swatches you need to configure them:

Please navigate to Dashboard -> Products -> Attributes -> Color -> Configure items, enable swatch as shown http://prntscr.com/jskm29 and add the color;

Navigate to Theme Settings > Shop > Attribute swatches > choose pa_color (your color attribute) and enable “Use images from product variations” if you want swatches to show variation image instead of the color;

Make sure each variation in a variable product has an image: http://prntscr.com/kk870w

As for the image on variation, please update your theme, today we have released the recent version and this problem has been fixed.

Best Regards
