Woocommerce gallery help

Hi, I need some help resolving an issue I have on my product gallery pages. I had an issue with corrupt database, so had to reinstall everything from scratch, piece by piece, I have nearly everything back but can't now get my product galleries working as they were before. I need a border or drop shadow on product gallery pages, some of my images are mainly pure white, as is my site background, so need something to show the edges. I can live without the drop shadow, but could really use a border round the images. Also on individual product pages the image used to be small and "fit the page" now it seems a set widtch, fine for landscape images, but portraits run off the screen. It's perfectly possible I'm an idiot and cannot find the settings somewhere, but please help :) Theme: Clean Fotografie Pro Website: https://www.urbanlakephotography.com example of where border needed: https://urbanlakephotography.com/product-category/fine_art_photography/
