Better method for image path?

Hey guys,
I’m new to this whole Flash website set-up, especially
using XML and the like.

I am setting up my own portfolio website, using Kirupa’s
image gallery tutorial. The images for this tutorial seem to
come from a url, while the ones for mine come from my
computer’s hard drive path. Is there a way I can also
use a url for my images? Will that help to optimize the site’s
performance?

I’m using godaddy to host my site, I feel like I should be able
to upload my images, and direct the path from there.

Lots of questions, :puzzle:
