Hello All,

I have to write a Java scrript to User not to upload Images for More than 45 kb. I have checked the Bible did not find anything related to images size Validation , Could you please help me with this.

You can check the size of the icon stream.

I have used this method but it's giving same value for diffrent images 

var im1 = this.getField(event.target.name);
// get the icon for image 1
var icon1 = im1.buttonGetIcon();
try {
var iconStream1 = util.iconStreamFromIcon(icon1);
var dd= icon1.toSource().length

Is this not correct?

Check the size of iconStream1

I did, it's showing "undefined "

How does you check the size?

You can't do it while they're selecting the image to prevent them from doing so. Maybe you can use an On Blur event on the button or the document's Will Save event to check the length of the icon stream, as mentioned, or even the file-size...
