Example of uploading photos upimage.php

Function: Upload photos, display uploader, upload time, picture name, picture size, picture description.

Note: 1. Some homepage spaces may not support temporary file operations after uploading, so you can only try another one.

2. The program can automatically create the document photo.txt and the directory image. If it cannot run normally, please create a new document photo.txt (in the same directory as upimage.php) and the directory image.
