We need to support a variety of image shapes and sizes. Images uploaded after the Wishlist was launched in December of 2019 have an uncropped and unpadded image that is ideally sized for high DPI mobile devices.
Images uploaded before December 2019 were automatically “cropped and padded” using a landscape dimension. In any case, you can customize the way the image fills the available space on the item card using CSS and the object-fit property. You can either “contain” the image (default) within the image area or “cover” it with the image. There are trade-offs for both, but this can be adjusted to whatever works best for you.
You can also upload new images; check out our article on Wishlist image size requirements here.
