Question

How can I get the size, height and width of an image in when upload it with jQuery?

Answer 1

if you use jquery uploadify plugin then you can find the file size by any one of these following method

'onSelect': function(event, ID, fileObj) {
    console.log(fileObj.size);
}

OR,

'onComplete': function(event, ID, fileObj, response, data) {
    console.log(fileObj.size);
}

and use

$('img').css('width');
$('img').css('height');
