The db should have stayed in a consistent image (probably with half
images registered). That's the db server duty, after all.

This doesn't make sense. You mentioned that you cleared cache, what
about memcached? (objectcache table if not using memcached).

It seems a db problem. Have you tried to eg. stop & restart the db
server? Which engine are you using?
What about running importImages *again*? (so that half-updated files get
added). You could also remove everything from image table, and readd
with importImages (well, you would lost the information on author and
upload time, although could be consulted through Special:Log).
