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
