Some folks have been inquiring about the sampel code that I had on my blog. Since my web host was changed and the content was lost, I've moved the code to CodePlex. I've pruned the samples, and made them availabled here. What's included:

• Converting WPF BitmapSource <-> GDI+ Bitmap
• Metadata Walker
• Using WPF InPlaceBitmapMetadataWriter

Also, the code for WICExplorer and WICCop are available from MSDN. They are available here. What's included:

• WICExplorer: Base bones metadata and image viewer built using WIC
• WICCop: Tool used to verify that the WIC CODEC Guidelines have been properly implemented. Also includes C# COM Interop interface definitions for WIC.
