How do i add the share button to the category and home page on the actual product thumbnail box as i used to have this feature on another theme before we changed to yours where we could share the product direct from search or home page or category page as there was a share button on the thumbnail box next to the quick view button and wishlist

also the images on home page grid are all not alingned and looks so messy why is this why are they all not on the same line also the product images are all diffrent sizes ive tried everything with no joy ive regenerated thumbnails and still no joy ?
