Neil,
Thank you for the reply. I still have not got my code to work the way I want it to work.

Please review and let me know where you think I am going wrong.

1. I added two images Img0.jpg and Img1.jpg to my solution
2. I changed the Build Action in the file properties to Embedded Resource.
3. In the constructor (after the InitializeComponent()) I have the following code:

oBitmaps = new Bitmap[2]; // Should I maybe use an array of images instead of bitmaps?

//System.Resources.ResourceManager oResMan = new System.Resources.ResourceManager("MyScreenSaver.frmMain",System.Reflection.Assembly.GetExecutingAssembly());
System.Resources.ResourceManager oResMan = new System.Resources.ResourceManager(typeof(frmMain));

oBitmaps[0] = (Bitmap) oResMan.GetObject("Img0.jpg");  // oResMan.GetObject("NetMasterLogo") returns null
oBitmaps[1] = new Bitmap("c:\\it\\Img1.jpg");  // this works and loads the image into the bitmap array

4. At another point in my application I set the image property of the picturebox using the code:

this.pictureBox1.Image = this.oBitmaps[iImage];

I don't really understand the code you have in button1_click. I thought the purpose of embedding an image into the exe through the build action of the file properties was that I didn't have to ship the image files but that they would be embedded in the exe.

I hope you can help me.

Thanks,
Einar
