Article Introduction：I have written an upload component before, see Creating an HTML5 File Upload Component, which implements progress display and drag-and-drop upload. It is compatible with IE6+ and other standard browsers. There is no problem with general uploads. However, if you are uploading pictures and need to preview, it is powerful. No more catching up, I took advantage of my free time to add a separate image upload UI to the upload component, which supports image preview and scaling (by adjusting the size of the image to achieve image compression).
