Could someone Please install gallery for me?

I am clueless on software installs is there any one that could install it for me, Please.

I am hosted with dot5hosting.com and see that they do have NetPBM installed. I have emailed their support and they tell me I can install it into my space and then install the gallery. I have really never done anything like this.

Our site is just a small family site to share kid stories and photos. We would love the gallery as right now we have a very limited php slideshow script.

Thanks for your time.
