Your custom control is dependant that your images must be placed in the web site that uses this custom control.
Why dont you embed the 3 images into your project and then after building your project copy those resources out of your project and place them into say "..\images\InformationLine\" directory and then automatically have your control reference them.
I'm a beginner now for 30 years; you should never stop learning; I found your article helpful; the only thing I would add is an icon to make the point of drag and drop from the toolbar; i.e. [ToolboxBitmap(typeof(InformationLine), "InformationLine.bmp")]
The requirement that he is suggesting is to make a bitmap to represent your control. Then you add this bitmap to your custom control directory. After that you should be able to build your custom control and then import it into your Visual Studio Toolbox with that bmp showing next to your control in the Toolbox.
