Registration Module-after a user registers, upload a large image. You can crop the large image and select your desired location.

When you register a user, you need to upload the user image. However, if you want the user to upload images too large, we will generate thumbnails, which will be distorted, the solution is to log on to 35 and ask the user to upload a large image. After the user uploads the large image, he can cut the desired position of the big image, in this case, users do not have to look for small images from other places as their own images, and my Js level is not high, so I have to deduct it (there will be no copyright issues). The source code will be published below. This function is very practical!
