Integation of imagex module and galleria

Galleria is good module but backwardness is we need to upload photo one by one so if we have more than 100 pictures it should be a hectic work. (still dont know is there any other way to upload several images at a time)

There is one module called "mulitple image upload" , below is the url:
http://drupal.org/project/imagex

It can only work with image module.

But how to integrate this imagex module to galleria module so that we can easily upload photos from our desktop to website.

Idea: May be when we attach image file by clicking browse at that time if we can integrate this imagex module then (for that specfic content type) we can easily upload images at a time )no need to attach images ne by one)
