Pichosting service, questions!

[RossMAN]

I setup the subdomain pics.gottadeal.com (I know it doesn't work currently)

1) I installed 4ImagesGallery here, http://www.gottadeal.com/gallery/ does this software suck compared to others which are free and EASY to install?
2) If I want the URL to be pics.gottadeal.com is it as simple as redirecting http://www.gottadeal.com/gallery/ to http://pics.gottadeal.com/ or is there a better solution?

This won't be a pichosting service for the public since we already have 5 pichosting services available, just for personal, business and family use.

Thanks!
