You mean the images from a website won't show in mIRC? Not sure why as I tried a few ways of breaking my alias and nothing gave me an image-free site. Try this in your alias file and see if it works. (Don't forget to change the filepath to the DLL, and of course the homepage)

Code:
ie {
  window -ak0p @Browser 0 0 800 600
  var %bs.bs $dll(nHTMLn.dll,attach,$window(@Browser).hwnd) 
  var %bd.bd $dll(nHTMLn.dll,navigate,http://iserv.com.au/)
}
