[Plugin: vSlider Multi Image Slider for WordPress] how to change the image order

hi, i have recently installed this plugin and it works fine, but i want to know if it is possible to change the order of the images, for example to move one before other without rewriting the image url.
I also want to know if you can post an external image link i.e without uploading the image to your server.

thanks
