hook to button action?

Easy enough to hide the ngg_uploader button, but how would I fire the proper function with my own button?

It just looks nicer to have the “Upload” button in my jQuery UI dialog() footer space, but the shortcode for the uploader is in the dialog body.

any suggestions?

Also, what about ngg_uploader callbacks?
Any way to hook into something that would fire on image_upload success?

thanks.
