The code is a little different from yours, but, this form should be revised, it is very simple when we add the reference in the project, but, I made an example dynamically loading the dll.

To library is called: Biblioteca.dll, the Resource (filing cabinet .resx) is called: Imagens.resx, the name to put it on builder of class ResourceManager is Biblioteca.Imagens, as it is in the code. Inside this Resource has 3 images with their names: _1, _2 and _3 which in this case is the value of GetObject.

Having that value (Object), make a cast (Imagem) and pass the value to PictureBox1.Image that the image will be loaded ...

string path = @"C:\Projetos\";
string real = System.IO.Path.Combine(path, @"Biblioteca.dll");

Assembly assembly = Assembly.LoadFrom(real);
ResourceManager resourceManager = new ResourceManager("Biblioteca.Imagens", assembly);
pictureBox1.Image = (Image)resourceManager.GetObject("_3");

Main reference of the code
