I have a program in C# with a PictureBox object inside a Form. How do I change its picture? The pictures to chose from are in bin/Pics; they are jpeg in format, if that matters..

Assign a new Image object to your PictureBox's Image property. To load an Image from a file, you may use the Image.FromFile method. In your particular case, assuming the current directory is one under bin, this should load the image bin/Pics/image1.jpg, for example:
pictureBox1.Image = Image.FromFile("../Pics/image1.jpg");
Additionally, if these images are static and to be used only as resources in your application, resources would be a much better fit than files.

2Of course, it depends on what you are going to do with the images. I prefer loading images from a
Streambecause theFromFile()method keeps the file handle open until the end of the applicaition life time. This can lead to unwanted side effects when you try to overwrite the image with a file that has the same name, for example.– Jens HCommented Jul 14, 2012 at 23:00 -
Just to add to the above, I couldn't get my images to display then remembered that you need to add double \\ s for example;pictureBox1.Image = Image.FromFile("C:\\Users\\bob\\Documents\\music.jpg"); Commented Dec 18, 2018 at 22:24

@HeavyHead If you decide to use backslashes instead of forward ones, sure. Forward slashes are valid path separators in Windows, so "C:/Users/bob/documents/music.jpg" will work in Windows too. If you're stuck on using backslashes then use a string literal to ignore the unintentional escape characters. i.e. @"C:\Users\bob\Documents\music.jpg" Commented Jun 12 at 14:57
If you have an image imported as a resource in your project there is also this:
picPreview.Image = Properties.Resources.ImageName;
Where picPreview is the name of the picture box and ImageName is the name of the file you want to display.
*Resources are located by going to: Project --> Properties --> Resources
You can use the ImageLocation property of pictureBox1:
pictureBox1.ImageLocation = @"C:\Users\MSI\Desktop\MYAPP\Slider\Slider\bt1.jpg";
