in windforumapp you would just do it like this:
img1.Image = Properties.Resources.image1;
but you can't do that in wpf. you can only do img1.Source. how do you make an image in wpf use a resources image?

To use a resource image in XAML, what you should actually do is set the build action for the image file to "Resource" (not "Embedded Resource", also don't add it to a .resx file). Then you can access the image from XAML with a pack:// url, e.g. (assuming the file is in a subdirectory of the project called Resources):
<Image Source="pack://application:,,/Resources/myfile.png" />
In code you could access it as follows:
BitmapImage img = new BitmapImage();
img.BeginInit();
img.UriSource = new Uri("pack://application:,,/Resources/myfile.png");
img.EndInit();
And you can use the following extension function to convert GDI+ bitmaps to WPF BitmapSources:
public static BitmapSource ToBitmapSource(this System.Drawing.Bitmap bitmap)
{
using( System.IO.MemoryStream stream )
{
bitmap.Save(stream, System.Drawing.Imaging.ImageFormat.Bmp);
stream.Position = 0;
var result = BitmapFrame.Create(stream, BitmapCreateOptions.None, BitmapCacheOptions.OnLoad);
result.Freeze();
return result;
}
}
