What wrong?

What settings have to be set so the image shows and not only the BackColor?

Brief diagnosis and a focused troubleshooting path that complements 's follow-up and the debugging nudges from and : when an image is visible in the designer but the PictureBox shows only its BackColor at runtime, the runtime Image reference is null (the designer-assigned resource isn't being found/loaded). The usual causes are (a) the designer serialized the image into a different .resx than expected, (b) the resource wasn't embedded/copied into the output, or (c) the designer generated a reference that the ResourceManager can't resolve at runtime.

Concrete checks and quick fixes to apply in order:

  • Pause execution immediately after InitializeComponent and inspect pictureBox1.Image in the debugger. This confirms whether the Image property is null at runtime.

  • Open the form's designer code and see how the image is assigned. Two common patterns appear:

    this.pictureBox1.Image = ((System.Drawing.Image)(resources.GetObject("pictureBox1.Image")));

    or

    pictureBox1.Image = Properties.Resources.MyImage;

    If the former is present, the image lives in the form's .resx; if the latter, it comes from the project's Resources. Verify the corresponding .resx or Properties\Resources.resx contains the image entry and that Resources.Designer.cs exposes the resource name.

  • Common fixes: ensure the form's Localizable property isn't unintentionally set (it moves control resources into the form .resx), re-import the image into the desired resource location, or assign the image explicitly in code to guarantee the correct resource is used:

    pictureBox1.Image = Properties.Resources.MyImage;

  • If the image was added as a file (not embedded), confirm its Build Action and Copy to Output Directory are correct (usually Content + Copy if newer), or embed it in project resources to avoid file path issues.

A final note: embedding many large images increases assembly size; use project resources for fixed UI art and external files for frequently changed assets. The debugger inspection that and suggested usually pinpoints which of the above is the culprit.

Many things could be wrong here. Without some code, I feel like a blind man trying to break an egg with a stick...
Btw how is the wife? All well?

Hahaha, so true. Turns out I figured out what the problem was. Or rather what caused it, I still don't know how to fix it.

When I import an image from Local Resource, the image shows up just fine.

When I use a Project Resource and click "Import", the picture shows up in the IDE, but when pressing F5 to test it, it doesn't show.

Any thoughts?
