Adobe Acrobat

How would I check for an image's size and reject images that are above a certain size, giving the user a pop up message telling them to choose a smaller file if they try to insert one thats too big?

I found this script that i've been trying to make work:

if(image1.value.image.value.length > 1400000)
{
this.validationMessage = "Image larger than 1MB . Please select a smaller image.";
0;
}

but it keeps giving me a 'validate failed' message.

Can anyone help me with this? I have very little javascript knowledge and just need to do this one thing that is driving me nutty.

I've tried around a bit, and finally I got it work with this script.

if(ImageField1.resolveNode("value.#image").value.length > 1048576){ImageField1.validationMessage = "Image larger than 1MB . Please select a smaller image."}

Here is an example file

But, this will not stop the import of the image it only will alert the user through the message.
