Can Javascript access native image size?

Question

I\'m writing a jQuery function where I\'d like to access both the native size of an image, and the size specified for it on the page. I\'d like to set a variable for each.

Answer 1

This should work:

var img = $('#imageid')[0]; //same as document.getElementById('imageid');
var width = img.naturalWidth;
var height = img.naturalHeight;

The naturalWidth and naturalHeight return the size of the image response, not the display size.

According to Josh' comment this is not supported cross browser, this might be correct, I tested this in FF3
