Amendment to the "Back to top" feature

Dear,

I have noticed something related to the new “back to top” feature. In fact, the only useful case where this feature would be used is when there are additional variation pictures uploaded for a specific variation. I think most users would agree with me.

Besides this situation, the feature has no point and the thing is that, I am happy with this new feature, but is there a possibility to amend it in such way that it occurs activated only when there are effectively pictures in the variations gallery?

Thanks a lot
