Given the disclaimer at
http://www.squid-cache.org/mail-archive/squid-users/200603/0022.html and
assuming it works like http_access rules (all ACLs are "AND-ed"
together), I would think you could use use the no_cache directive.
Something like...

acl greater_than_2K rep_header Content-Length [3-9][0-9]{0,3} # Match a
size of 3000 through infinity
acl jpeg rep_mime_type image/jpeg
no_cache deny jpeg !greater_than_2K # Don't cache JPEGs unless they are
reported greater than 2999 bytes in size

...should prevent caching small JPEGs from servers that correctly
identify both the content type, and size of said images, though I think
it would also prevent the caching of JPEGs that have no reported size.
*shrug*
