This is the topic that I posted How to refresh or show immediately in datagridview after inserting?. I uploaded a image, but it didn't display. Is it the website problem?
Perhaps you get a 502 Proxy error.
If you use Chrome, you can take a look at the Console output. For example, I don't get to see the image either, but Chrome tells me
Failed to load resource: the server responded with a status of 502 (Proxy Error ( Company denied the specified Uniform Resource Locator (URL). ))
