I imagine that you define your image something like this    lt img id  image portrait  src    alt  chef etat   width  120  height  135     gt    You can simply load update image for this tag and chage set atts  width height    var imagelink  var height  var width      image portrait   attr  src   imagelink       image portrait   attr  width   width       image portrait   attr  height   height

Here is the code I use when I want to preload images before appending them to the page   It is also important to check if the image is already loaded from the cache  for IE          create image to preload      var imgPreload   new Image          imgPreload  attr           src  photoUrl                check if the image is already loaded  cached       if  imgPreload complete    imgPreload readyState     4               image loaded            your code here to insert image into page        else             go fetch the image            imgPreload  load function  response  status  xhr                if  status     error                        image could not be loaded                 else                      image loaded                    your code here to insert image into page

after you get the image path  try either of following ways    as you need to set more attr than just the src  build the html and replace to the target region      target div   html   lt img src     imgPaht     width 100 height 100 alt  Hello Image    gt      you may need to add some delay if changing the  SRC  attr  setTimeout function      this function fire after 1ms delay           target img tag id   attr  src  imgPaht      1
