What do you mean by Storage Space size?  What kind storage disk storage.  Photoshop ram requitements Pictures can be quite complex they can have  up to  8,000 layers.

And what storage space + file format?

You could save a file somewhere temporarily and then read the filesize from that temporary location before moving it to where you want it to go eventually.

This is the filesize part:

#target photoshop;
var fileRef = "C:/myImage.jpg";
var x = new File( fileRef ) ;
alert(x.length);

On windows, if you have an image at this location C:/myImage.jpg it will work.
