Smaller Product Thumbnails and One Page Scroll Effect

Hi HB-Themes,

(1) I need help to downsize my product thumbnails on this page for desktop view. They look alright on mobile. Attached screenshot http://www.fancyupevents.com/event-design-styling/#event-design-package

Also, may I know is there a way to make the product images clearer or I just need to upload larger ones?

(2) I have a navigation buttons on http://www.fancyupevents.com/event-design-styling/ to scroll to later half of the page #event-design-package and #dessert-table-package. Is it possible to add a scroll down animation/effect? May I know how I can go about doing it?

Thank you very much for your assistance.
