I was asked recently how to embed and retrieve bmp file into your dll file. I’d like to take credit for figuring it out but I’m sure I originally saw it on Jeremy’s site somewhere.  Here is how I do it:

Add the image as a resource to the project

From the project menu select properties

On the resource tab select add resource

 Browse and find the image.

Once selected it should be listed in the solution explorer under the resources folder

Set the image property to embed

In the solution explorer find the image and right click and go to properties

 Set the build action to embed

Add a reference to  PresentationCore.dll

Once this is done you can use this code to retrieve the image.
