resize images on demand before upload

1.) jpg, no resize: original file is uploaded

2.) jpg, resize demanded: thumbnail is uploaded

3.) other files: original file is uploaded

the code:

var imageUploader = $au.uploader({

...

converters: [
                      { mode: '*.jpg=Thumbnail;*.*=SourceFile', thumbnailWidth: 10000, thumbnailHeight: 10000  }
                      ],

});

2 input fields with height and width override: 'client_x', 'client_y'

function beforePackageUploadHandler()
              {
                    client_x = parseInt(document.getElementById('client_x').value)
                    client_y = parseInt(document.getElementById('client_y').value)

                    if ((!isNaN(client_x)) && (!isNaN(client_y)))
                       {
                       var c = imageUploader.converters().get(0);
                       c.thumbnailWidth(client_x);
                       c.thumbnailHeight(client_y);


                     }
                     else
                     {
                        var c = imageUploader.converters().get(0);
                       c.thumbnailWidth(10000);
                       c.thumbnailHeight(10000);


                     }

                }

So, if no resize is demanded, the thumbnail is set 10000x10000 (and the image won`t be touched, because its smaller)

This works great on localhost, but on my productive server I get the message that the thumbnails are too big for the license. (if no resize is demanded and the thumbnail is resized to 10000 x 10000, which would not happen)

So, instead of setting the thumnail to a big size that would not be fired, I have to remove the

{ mode: '*.jpg=Thumbnail;*.*=SourceFile', thumbnailWidth: 10000, thumbnailHeight: 10000  }

and rewrite the function beforePackageUploadHandler that only thumbnails are generated if demanded.

Any ideas?

bst regards

Image Uploader Express supports thumbnails of size 3Mpix and less. Returning to your code, say, client_x = 2000 and client_y = 2000, in this case it will be 4Mpix (2000 x 2000 = 4 000 000), this thumbnail does not work with Express edition.
