How to create deb package with screenshot for Ubuntu?

Question

I've create a deb package using instructions from launchpad and put it in PPA, and I want to include the screenshot to be displayed in SoftwareCenter.

and additionally I want to provide Licence and Updates (when I select my package it show undefined or unknown - I have localized version of Ubuntu)

Answer 1

If you upload a screenshot to http://screenshots.debian.net/ it will be displayed in SoftwareCenter and Synaptic. Although I'm not sure if that applies to packages from PPAs, they might have a different method or no screenshots at all.
