As we all know, a program contains some resources. If there are image resources in it, we can get an image, resources in the SRC local program, if onerror, it indicates that the program is not installed, but it may be installed on disk D, disk E, or other paths. In this case, the program cannot be installed on the default path. If a program developer releases an image to a fixed local directory no matter which disk the program is installed on, it is used to determine how good it is! Of course, it is better to judge the HTTP header, which is simple and effective.
