I think this needs to be clarified. Subversion works equally well for
text and binary files. Locking works. The bit that doesn't work with
binaries is trying to merge changes when two users change a file
simultaneously. And that is the whole point of locking, to prevent two
users changing the same file.

Because locking is not the default in Subversion there are a few
things your need to consider when using it. You need to set the
svn:needs-lock property on every binary file. It is possible to set up
client-side rules to apply this property automatically, but to be
really safe you may want to set up a server-side hook to ensure that
no file is ever added to the repository without that property.

What that property does is make every file which has not been locked
read-only. When you take a lock the file becomes writeable. This is
what gives you your local protection against modifying a file without
taking a lock. However it does rely on your software telling you
straight away that the file is read-only and not letting you modify
it. If your image editor only tells you that when you come to save
changes after forgetting to take out a lock, then it could get
frustrating.

When Bob says that locks aren't enforced what (I think) he means is
that there are commands to break a lock (i.e. remove a lock which
someone else has taken out) and steal a lock (remove someone else's
lock and lock the file yourself). This can allow anti-social behaviour
where someone decides their changes are more important than yours and
steals your lock so they can commit changes and yours get discarded.
But that is more of a community behaviour issue rather than a problem
with locking per se. The reason for these commands is that if someone
takes a lock and then goes on holiday without releasing it, then
everyone else is stuck until they get back. If you are really paranoid
then it is possible to set up server hooks to prevent locks being
broken or stolen, but that is not generally recommended.

Also, if you are working as a team then using a proper server is a
must. Do NOT be tempted to use a shared NAS drive or similar and just
pretend it is a local repository. Fortunately there are several
friendly Windows installers for Subversion which will take you through
the installation and setup using a wizard front end. Three of them are
mentioned at the bottom of this manual page:
