Question

EDIT: Reworked my code a bit and decided to throw out URLLoader in favor of the File.upload() method.

Now I’m stuck again >_<

Here’s the code I currently have, stripped down to bare-bones: https://gist.github.com/1943401

When I drag-drop image files onto my app, here is the trace log that gets returned to me:

[object Document] called.
doDragEnter() called.
doDragDrop() called.
file Extension Check = passed
Uploading files: C:\testimage.jpg

I did something similar to Todds alternative. Basically I had to upload each image asynchronously (one at a time).

So I created an array of images and created an integer (i) counter starting at 0.

uploadImage(imagesArray[i]);

Each time I uploaded an image the COMPLETE event was called.

within the complete event function the counter was incremented. If the counter was less than the length of the imagesArray I would then
e.g.

i++
if (i < imagesArray.length) {
uploadImage(imagesArray[i]);
} else {
//all images have been uploaded.
//reset vars
i = 0;
imagesArray = [];
}
