Is there server based gallery grabber script that I can buy?
 

Or stan alone solution where I can give the url and name I want to save it with?

define gallery grabber script.

you give it URL of FHG and it rips it and puts it on your server. So instead of using FHG links you have it hosted on your own server.

I have a FHG ripper that just strips the images from the gallery i can sell you.

Maybe this will help you out. I use it with success.
