I've made imageio.d and imageio.lib which has
libpng(+zlib) libjpeg inside and I am going to publish the whole
project in a week or two.

Meantime if anybody needs them now just drop me a message

imageio.lib compiled using dmc and make file provided

imageio.d file is simple:
--------------------------
module imageio.imageio;

version (Windows) { pragma(lib, "imageio\\imageio.lib"); } // weird , 
Windows supports / in paths
else {  pragma(lib, "imageio/imageio.lib"); }

// PNG and JPEG image decoder/encoder library
extern (C)
{
  // callback image ctor
  alias int function(void* prm, uint width, uint height, int bytesPerPixel, 
ubyte** rowPtrs) ImageCtor;
  // image decoder by itself
  int DecodeImage(ImageCtor pctor, void* pctorPrm, ubyte* src, uint 
srcLength);
}
---EOF-----------------


Fragment of real code which uses it and creates Win32 DIB:

extern(C) int DibCtor(void* pctorPrm, uint width, uint height, int 
bytesPerPixel, ubyte** rowPtrs)
{
  Dib im = cast(Dib)pctorPrm;
  im.init(size(width,height),bytesPerPixel);

  for(int i = 0; i < height; ++i)
    rowPtrs[i] = im.rowBytes(i).ptr;

  return 1;
}

class Dib
{
....
       // creates Dib from PNG or JPEG encoded bytes.
       static Dib create(ubyte[] bytes)
      {
          Dib d = new Dib();
          if(d.DecodeImage(&DibCtor, d, bytes.ptr, bytes.length))
              return d;
          delete d;
          return null;
      }
      // loads Dib from PNG/JPG file
      static Dib load(char[] path) { .... }

}

As you may see image rendered on top of input widgets.

Solely HTML GUI is unpractical. Too many reasons.
Embedded HTML used as universal layout manager and simple viewer
of e.g. html documents (help, tooltip) does make sense.
In short : use cases are similar to what XUL (Mozilla) is used for 
currently.

In any case it will be reduced HTML tightly integrated with the rest of the 
framework.
E.g. it will be possible to say:

hPanel.load(
"<p>And your age is: " ~ new NumericBox(0,150) ~ " years</p>");

far.

The intention is to provide a solid foundation for crossplatform UI 
framework
(and yet practical!)  and at current stage I did not finished even its 
basement.
But it is close.
