[koxu1996]

Steps to reproduce the issue

1. Open fiddle
2. Select multiple images (larger than 50px height) at once
3. fileimagesresized is not fired!

What cause this

In this commit 755bab1 you change code:

var counter = {val: 0};
for (i = 0; i < self.loadedImages.length; i++) {
    ..
    // notice that counter is global, because it is passed by reference!
    .. self._getResizedImage(.., counter, ..) ..
    ..
}

to this

for (i = 0; i < self.loadedImages.length; i++) {
    ..
    .. self._getResizedImage(.., {val: 0}, ..) ..
    ..
}
