If you have 8.1? If yes:

test=# select * from foo;
loc
-------------------
/0/v.myimage.jpg
(1 row)
test=# update foo set loc = regexp_replace(loc, '/v\.', '/');
UPDATE 1
test=# select * from foo;
loc
-----------------
/0/myimage.jpg
(1 row)
If no:
a) Upgrade now!
b) write a funcion with plperl for the regexp_replace
