Open Source Document Management System | OpenKM

Hi, First time in the forum. I have install openkm in my laptop and using the community version 6.3.0 build 8156. I could not see thumbnails of PDF files. Is it disabled in community edition? Second question, is it possible to use custom thumbnails? I am trying to use OPENKM for chemistry and would like to have a picture of molecule/s as thumbnail instead of a text page in thumbnail.

This feature is only present in professional edition. About get your own picture, the thumbnail feature is based on plugin system, that means if you got an application what can convert documento to picture from terminal, we can configure as a plugin for doing this operation from OpenKM as a plugin what does application wrapper.
