Load image from URL to pictureBox

Question

I'm trying to load several images from URLs to a pictureBox. My problem is that "pictureBox.Load(URL)" or "pictureBox.ImageLocation = URL" doesn't work. I don't know why, I think it is because the URL doesn't have an extension like .jpg.

private void button3_Click(object sender, EventArgs e)
{
    string URL = "https://internetmarke.deutschepost.de/internetmarke/franking/image/view/1403556118.do";
    pictureBox1.ImageLocation = URL;
}

The URL works in Firefox and the picture is shown. But in IE it doesn't work and I think that's the same reason why it's not working in .NET.

IE says "unknown filetype" and wants to download a "1403556118.do" file.

In C# I only get a red X in the pictureBox.

When I first try to load it in IE, it works in the pictureBox (IE cache?)

Does somebody knows another possibility to load this images to a pictureBox?

EDITED: Added sample code.

---

Today I've tested the code on three different computers and with different Internet connections; Home DSL, Company DSL and a UMTS/3G Surf-Stick. All without any proxies and also tested without virusscan.

In every single scenario it didn't work, same as I wrote in my first post.

After I accessed some of the URLs in Firefox or IE, the images of these URLs showed up in my application. All others remained a red X.

Is there any different (old-school^^) method to load these images, like downloading the HTTP-Stream into a byte array and then copy this into pictureBox.Image or something?

Answer 1

pictureBox1.ImageLocation = "http://www.micoequipment.com/products/large/MF_260_l.jpg"; //should work

Make sure that image is accessible via web browser (test it before). Also, please make sure that you are calling correct picture box :) It works for me.

Answer 2

@Andrew:

pictureBox1.ImageLocation = "http://www.micoequipment.com/products/large/MF_260_l.jpg";

This Works!

pictureBox1.ImageLocation = "https://internetmarke.deutschepost.de/internetmarke/franking/image/view/1403556118.do";

This doesn't work!

Your link and my link both work in Firefox. But my link doesn't work in IE and it doesn't work in .NET and in the pictureBox.

Answer 3

这应该可以工作，因为您是从远程 URL 加载图像：

pictureBox1.Load(URL);
