You're initializing photograf as a string, which has no width() or height() functions. Nowhere are you actually attempting to load an image, with jQuery or otherwise. In fact, there is no jQuery anywhere in your code.

You could either add the image to the page, and then find the resulting element's width/height, or create a new Image object:

photograf = new Image();
photograf.src = 'upload/' + nm + '.jpg');
var width = photograf.width;
var height = photograf.height;

Given that you tagged with jquery, this is the jquery way to do what meagar has written:

var photograf = $("<img src='upload'"+nm+".jpg />");
var imgWidth = photograf.width;
var imgHeight = photograf.height;
