the front page of the project is similar to the following figure, Taobao merchandise interface. Below, you need to show a few small pictures of rotation, and then click on the specific small picture, which shows the larger image.
now I am responsible for the backend management page of the store. In consultation with the backend engineer, they suggest that the front end find a way to achieve this function: when a picture is selected to be uploaded, two pictures, a large image and a small image, are saved when uploaded to the background. In this way, the merchandise page in the store can get two pictures.
could you tell me how to implement this?
