As cron_cssstyledimgtext was integrated into css_styled_content in
4.0.0, I would simply de-install cron_cssstyledimgtext. After that, go
to the install tool and check the "Upgrade wizard" and tell him you want
to use the new behaviour. Then just clean your TS-template (constants
and setup) from any setting regarding tt_content.image or
tt_content.textpic, and see if the new default behaviour is not exactly
what you need already.

Also note that altText and other fields that were previously added by
cron_cssstyledimgtext are now part of the core, but without the
extension prefix, so you might want to run some "UPDATE" SQL statements
to update that info.

Cheers,
