as3 xml Slideshow - actionscript-3

Question

Below is the code of my slideshow, the problem I am having is that after 1st image that loads has the perfect size which I needs but the second image loads has different size I want it to be of same size as of 1st one. Also the images are not loading in a sequence. Can any expert figure out and solve the problem.

Here is the xml
<xml>
<images><pic>portfolio1.jpg</pic></images>
<images><pic>portfolio2.jpg</pic></images>
<images><pic>portfolio3.jpg</pic></images>
<images><pic>portfolio4.jpg</pic></images>
<images><pic>portfolio5.jpg</pic></images>
</xml>

Answer 1

I don't think theImage's height represents image height after loading. That should be available with loader. To accommodate for different sized images, you'd have to bring actual height/width of image while applying scale. Else, of course, you can pre-resize all the images to same size.
About random loading, that's exactly what
currPainting=Math.floor(Math.random()*imageArray.length);
in beginImage is doing. To have the loading done in order, you can pick up 0th element directly.
