Yes. Add a single no_cache line.

acl images \.gif$ \.jpg$
no_cache allow images

The above use of refresh patterns won't deny caching of other content.
If the server has set an expiry time then the object will be cached
regardless of any refresh_pattern settings. Also most versions of Squid
will cache all cachable objects even if it immediately needs to be
refreshed. This is because in most configurations a refresh is
considered to be cheaper than a full fetch.
