After a brief session with the developers the following things were
done to fix the problem.

1. SQLAlchemy upgrade, it was SQLAlchemy==0.6.3.
2. git pull from the latest from master, chance noticed in app.py,
after this error's disappeared and successful upgrade message starting
appearing for video and jpg images as well. Earlier it appeared it
happened only for the png images.  (I don;t understand the reason why?
 may be png does not need any additional processing of the image?)
3. celeryd was not running, so ran the easycelery.sh.

Currently running two scripts: paster and easycelery.sh.

The site is now working fine.

There are two other issues, which I will report in another thread
