i am interesting in install zenphoto but before i need some information

1. Can i make friend url of zenphoto

2. Can i import images from my previous gallery along with category

1. I am sorry, I fear I don't understand the question.

2. Import from what type of gallery? From Zenphoto? Yes, please read here: https://www.zenphoto.org/news/moving-and-changing-existing-installations/
   Generally Zenphoto is file system based so folders with images and/or folder are recognized as albums. Text data entered in another system are not imported unless embedded as meta data into the images itself. There are some third party scripts for Menalto Gallery. Please see the extensions section.

@ kora:

Yes, with ZenPhoto you can have/create nice, userfriendly URLs.
