I've never built a website before and i think im doing really well so far. Im an artist and im building a site that can act as both a portfolio as well as a shop to sell from. My main issue right now is that the images are loading perfect onto the page but when you hit the quick view button or view full image the aspect ratio cuts off the image. I have a variety of painting sizes but every time i set the aspect ratio to fit one picture it changes it across all of them so then what works for one image ends up cutting off a good amount of another. I still haven't published the site bc I want to work out the kinks and add my bio but if someone can take a look and give me some tips i would appreciate it. I really don't want to hire a whole professional builder just to fix such a small issue. link to the page. https://www.4thplanetarts.com/ the password is: hiphop
