Size of product photo & Zoom

Hello,

I don’t know if my problem comes from the WordPress update or the spreadplugin update. I updated both at the same time… ??

My issue is that the product photo of my spreadplugin product page which is positionned on left, displays too big. I think 600×600. And so the description/details of the spreadplugin product, which was on the right, now goes on bottom.

Do you know where the problem could come from ?
Thank you for the help.
