Hi theinnovatorssrl,

Thanks for details, but it is not admin account.

But, in order to use Image swatches instead of Color swatches, please navigate to Products > Attributes > Configure term value of attribute > disable / remove the color swatch and enable the option Image swatch or Color swatch

Please check this manual:
