Can anyone help me. I want to change field name 'desc' in zp_albums to other name. Where can I change this?

Why do you want to do this? It will make your installation impossible to keep up with zenphoto changes in the future.

Anyway, if you really want to do it, you will have to rename the filed name in the MySQL administration and change all the references to it in in zenphoto. Beware that the same field is used in the images table.
